--[[User:Spuck|Spuck]] 09:26, 15 October 2008 (PDT) We have the following software working on our computers - Spot, Leopard, Mopex, MaxIm DL, and DS-9.

--[[User:Spuck|Spuck]] 09:30, 15 October 2008 (PDT) We used Leopard to downloaded all of the PBCD data for our Spitzer observations of LDN425 and LND981. We have started to do some visual inspection of the images, and making color composite images.

--[[User:JButchart|JButchart]] 3:15, 15 October 2008 (PDT) Shana and I looked through the LDN 981 data on Mopex and found some points of interest.. they are the following:

--[[User:AlixHolcomb|AlixHolcomb]] 05:21, 22 October 2008 (PDT) I look through the LDN 981 data on Mopex as well and found a few points of interest. They are as follows:

--[[User:AlixHolcomb|AlixHolcomb]] 05:33, 22 October 2008 (PDT)I also made some pretty sweet color composite images of LDN 981 using Mopex. Ch4(Green) Ch3(Red) Ch1(Blue):

--[[User:Jbutchart|Jbutchart]] 05:36, 28 October 2008 (PDT) I thought I would put up a festive color composite to celebrate Halloween and fall! Also, the spot at 21h 00m 07s, +50d 13m 04s can be seen quite well.

--[[User:Skennedy|Skennedy]] 05:51, 29 October 2008 (PDT) I found some information about a star previously known in LDN 981. Here's the abstract from the Astrophysical Journal.

'''ABSTRACT''' We characterize the small- and large-scale environment of the young star V1331 Cygni with high-resolution HST WFPC2 and Digitized Sky Survey images. In addition to a previously known outer dust ring (≈ in diameter), the WFPC2 scattered light image reveals an inner dust ring for the first time. This ring has a maximum radius of ≈ and is possibly related to a molecular envelope. Large-scale optical images show that V1331 Cyg is located at the tip of a long dust filament linking it to the dark cloud LDN 981. We discuss the origin of the observed dust morphology and analyze the object's relation to its parent dark cloud LDN 981. Finally, based on recent results from the literature, we investigate the properties of V1331 Cyg and conclude that in its current state the object does not show sufficient evidence to be characterized as an FU Ori object.

--[[User:Jbutchart|JenniferButchart]] 10:49, 29 October 2008 (PDT) I got on ADS today and found the same article (by Quanz, S. P.; Apai, D.; Henning, Th.) titled Dust Rings and Filaments around the Isolated Young Star V1331 Cygni. It is the same one as Shana found. I do believe these are the points they identified:

--[[User:Jbutchart|JenniferButchart]] 05:29, 31 October 2008 (PDT) I just read that entire article on astro-ph (found here: [http://lanl.arxiv.org/PS_cache/astro-ph/pdf/0610/0610786v1.pdf astro-ph]) and it says V1331 Cyngi is, mostly likely, the only star that has formed in LDN 981 (it formed in isolation). However, they stated that stars may form along the filaments of the cloud since it it undergoing a graviational collapse.

--[[User:AlixHolcomb|AlixHolcomb]] 11:26, 31 October 2008 (PDT)So I know it was like hours ago, but Spuck wanted someone to post about our video confrence. So I decided too. We established that the Oil City team needs to start making SED's and color color plots. I'm currently trying to conquer FITS liberator so that our color composite images turn out not as pixilated and a little less generic RBG. I'm sorta getting the handle of everything. I"ll post later.

--[[User:Jbutchart|JenniferButchart]] 21:07, 1 November 2008 (PDT) Alix, I posted about the video conference [with screen shot] under the video conference section right after we hung up.

--[[User:Rachele|Rachele]] 10:43, 4 November 2008 (PST) Jenni and I collected everyone's points of interest. We generated this table and will soon have x coordinates, y coordinates, magnitudes and intensities. This is in increasing order of RA.

[[Image:Wiki.JPG]]

--[[User:Jbutchart|JenniferButchart]] 15:47, 30 November 2008 (PST) Just a little update... We are working on getting all of the intensity, magnitude, and flux (Jy) values for all of the interesting targets in LDN 425 and LDN 981 (in IRAC 1, 2, 3, 4 and MIPS 1). We are using MaxIM DL for this procedure. We have a master spreadsheet that we will post when completed.

--[[User:Jbutchart|JenniferButchart]] 05:39, 3 December 2008 (PST) Here are all of my charts for LDN 981 in IRAC 1 and Mips 1. All of the targets are taken from what everyone posted.

--[[User:Jbutchart|JenniferButchart]] 13:51, 5 December 2008 (PST) I have completely figured out FITS Liberator... It's really simple, prior to contrary belief. :) Here's a nice color composite.. IRAC 1 = red, IRAC 2 = purple, IRAC 3 = green, IRAC 4 = blue.

--[[User:Jbutchart|JenniferButchart]] 05:46, 10 December 2008 (PST)Here's a color composite with IRAC 1,2,3,4 and MIPS 1.
[[Image:LDN981_withmips_small.jpg ]]

=Manhasset Discussion=

Students in class have identified the following points of interest in LDN 981.
Leopard was used to determine these candidates but MOPEX, ATP, and Spot are also downloaded and installed.

[[Image:981_so_far.jpg]]

The primary criteria for choosing these candidates was IR excess and oversaturated pixels.

[[Image:newfile.jpg]]

Of the 14 candidates above, we found references for 6 candidates:
candidates 1, 3, 6, 7, 11, and 13.

We followed Mr. Spuck's directions and came up with an overlay of 3 wavelengths: MIPS 24 in red, IRAC 8 in green, and IRAC 4.5 in blue. We located the stars that appeared to have a red ring (dust) and added them to our list of candidates.

Here is the list of candidates we found using this method of overlaying:

Here are our SED's for our candidates 1-4, 6-9:

= Chippewa Hills Discussion =

We have Spot and Leopard installed in our science department lab at school. They have been updated to the most recent version. Mopex is also installed and updated. APT will be done soon.

All PBCD data for both dark nebulae have been downloaded as well. We will look at what's been done at Oil City and Manhasset and see if we see the same points of interest, possibly identifying additional (if any) ones.

We now have a short list of additional points of interest. We believe that there may be more and I will have my astronomy students looking this coming week during class. Justin and Trevor are in this class and will be working with the other students to help them see what we are looking for.

Leopard was used to determine these candidates but MOPEX, ATP, and Spot are also downloaded and installed.

[[Image:981_so_far.jpg]]

The primary criteria for choosing these candidates was IR excess and oversaturated pixels.

[[Image:newfile.jpg]]

Of the 14 candidates above, we found references for 6 candidates:
candidates 1, 3, 6, 7, 11, and 13.

We followed Mr. Spuck's directions and came up with an overlay of 3 wavelengths: MIPS 24 in red, IRAC 8 in green, and IRAC 4.5 in blue. We located the stars that appeared to have a red ring (dust) and added them to our list of candidates.

Here is the list of candidates we found using this method of overlaying:

We have Spot and Leopard installed in our science department lab at school. They have been updated to the most recent version. Mopex is also installed and updated. APT will be done soon.

All PBCD data for both dark nebulae have been downloaded as well. We will look at what's been done at Oil City and Manhasset and see if we see the same points of interest, possibly identifying additional (if any) ones.

We now have a short list of additional points of interest. We believe that there may be more and I will have my astronomy students looking this coming week during class. Justin and Trevor are in this class and will be working with the other students to help them see what we are looking for.

--[[User:Jbutchart|Jbutchart]] 05:36, 28 October 2008 (PDT) I thought I would put up a festive color composite to celebrate Halloween and fall! Also, the spot at 21h 00m 07s, +50d 13m 04s can be seen quite well.

[[Image:Halloween.jpg]]

--[[User:Skennedy|Skennedy]] 05:51, 29 October 2008 (PDT) I found some information about a star previously known in LDN 981. Here's the abstract from the Astrophysical Journal.

'''ABSTRACT''' We characterize the small- and large-scale environment of the young star V1331 Cygni with high-resolution HST WFPC2 and Digitized Sky Survey images. In addition to a previously known outer dust ring (≈ in diameter), the WFPC2 scattered light image reveals an inner dust ring for the first time. This ring has a maximum radius of ≈ and is possibly related to a molecular envelope. Large-scale optical images show that V1331 Cyg is located at the tip of a long dust filament linking it to the dark cloud LDN 981. We discuss the origin of the observed dust morphology and analyze the object's relation to its parent dark cloud LDN 981. Finally, based on recent results from the literature, we investigate the properties of V1331 Cyg and conclude that in its current state the object does not show sufficient evidence to be characterized as an FU Ori object.

--[[User:Jbutchart|JenniferButchart]] 10:49, 29 October 2008 (PDT) I got on ADS today and found the same article (by Quanz, S. P.; Apai, D.; Henning, Th.) titled Dust Rings and Filaments around the Isolated Young Star V1331 Cygni. It is the same one as Shana found. I do believe these are the points they identified:

--[[User:Jbutchart|JenniferButchart]] 05:29, 31 October 2008 (PDT) I just read that entire article on astro-ph (found here: [http://lanl.arxiv.org/PS_cache/astro-ph/pdf/0610/0610786v1.pdf astro-ph]) and it says V1331 Cyngi is, mostly likely, the only star that has formed in LDN 981 (it formed in isolation). However, they stated that stars may form along the filaments of the cloud since it it undergoing a graviational collapse.

--[[User:AlixHolcomb|AlixHolcomb]] 11:26, 31 October 2008 (PDT)So I know it was like hours ago, but Spuck wanted someone to post about our video confrence. So I decided too. We established that the Oil City team needs to start making SED's and color color plots. I'm currently trying to conquer FITS liberator so that our color composite images turn out not as pixilated and a little less generic RBG. I'm sorta getting the handle of everything. I"ll post later.

--[[User:Jbutchart|JenniferButchart]] 21:07, 1 November 2008 (PDT) Alix, I posted about the video conference [with screen shot] under the video conference section right after we hung up.

--[[User:Skennedy|Skennedy]] 05:51, 29 October 2008 (PDT) I found some information about a star previously known in LDN 981. Here's the abstract from the Astrophysical Journal.

'''ABSTRACT''' We characterize the small- and large-scale environment of the young star V1331 Cygni with high-resolution HST WFPC2 and Digitized Sky Survey images. In addition to a previously known outer dust ring (≈ in diameter), the WFPC2 scattered light image reveals an inner dust ring for the first time. This ring has a maximum radius of ≈ and is possibly related to a molecular envelope. Large-scale optical images show that V1331 Cyg is located at the tip of a long dust filament linking it to the dark cloud LDN 981. We discuss the origin of the observed dust morphology and analyze the object's relation to its parent dark cloud LDN 981. Finally, based on recent results from the literature, we investigate the properties of V1331 Cyg and conclude that in its current state the object does not show sufficient evidence to be characterized as an FU Ori object.

--[[User:Jbutchart|JenniferButchart]] 10:49, 29 October 2008 (PDT) I got on ADS today and found the same article (by Quanz, S. P.; Apai, D.; Henning, Th.) titled Dust Rings and Filaments around the Isolated Young Star V1331 Cygni. It is the same one as Shana found. I do believe these are the points they identified:

--[[User:Jbutchart|JenniferButchart]] 05:29, 31 October 2008 (PDT) I just read that entire article on astro-ph (found here: [http://lanl.arxiv.org/PS_cache/astro-ph/pdf/0610/0610786v1.pdf astro-ph]) and it says V1331 Cyngi is, mostly likely, the only star that has formed in LDN 981 (it formed in isolation). However, they stated that stars may form along the filaments of the cloud since it it undergoing a graviational collapse.

--[[User:AlixHolcomb|AlixHolcomb]] 11:26, 31 October 2008 (PDT)So I know it was like hours ago, but Spuck wanted someone to post about our video confrence. So I decided too. We established that the Oil City team needs to start making SED's and color color plots. I'm currently trying to conquer FITS liberator so that our color composite images turn out not as pixilated and a little less generic RBG. I'm sorta getting the handle of everything. I"ll post later.

--[[User:Jbutchart|JenniferButchart]] 21:07, 1 November 2008 (PDT) Alix, I posted about the video conference [with screen shot] under the video conference section right after we hung up.

--[[User:Rachele|Rachele]] 10:43, 4 November 2008 (PST) Jenni and I collected everyone's points of interest. We generated this table and will soon have x coordinates, y coordinates, magnitudes and intensities. This is in increasing order of RA.

--[[User:Jbutchart|JenniferButchart]] 02:34, 16 November 2008 (PST) Here are the previously identified targets in LDN 981... (Don't ask why I'm up so late.. I love Arizona!)

[[Image:Wiki.JPG]]

--[[User:Jbutchart|JenniferButchart]] 15:47, 30 November 2008 (PST) Just a little update... We are working on getting all of the intensity, magnitude, and flux (Jy) values for all of the interesting targets in LDN 425 and LDN 981 (in IRAC 1, 2, 3, 4 and MIPS 1). We are using MaxIM DL for this procedure. We have a master spreadsheet that we will post when completed.

=Manhasset Discussion=

Students in class have identified the following points of interest in LDN 981.
Leopard was used to determine these candidates but MOPEX, ATP, and Spot are also downloaded and installed.

[[Image:981_so_far.jpg]]

The primary criteria for choosing these candidates was IR excess and oversaturated pixels.

[[Image:newfile.jpg]]

Of the 14 candidates above, we found references for 6 candidates:
candidates 1, 3, 6, 7, 11, and 13.

We followed Mr. Spuck's directions and came up with an overlay of 3 wavelengths: MIPS 24 in red, IRAC 8 in green, and IRAC 4.5 in blue. We located the stars that appeared to have a red ring (dust) and added them to our list of candidates.

Here is the list of candidates we found using this method of overlaying:

[[Image:Mips_candidates.JPG]]

== Chippewa Hills Discussion ==

We have Spot and Leopard installed in our science department lab at school. They have been updated to the most recent version. Mopex is also installed and updated. APT will be done soon.

All PBCD data for both dark nebulae have been downloaded as well. We will look at what's been done at Oil City and Manhasset and see if we see the same points of interest, possibly identifying additional (if any) ones.

We now have a short list of additional points of interest. We believe that there may be more and I will have my astronomy students looking this coming week during class. Justin and Trevor are in this class and will be working with the other students to help them see what we are looking for.

=Lynds clouds=

In the early 1960s, Beverly Lynds studied the Palomar Observatory Sky Survey (POSS) plates and made a list of things she thought were bright or dark nebulae. These of course were subjective judgements, but they are often pretty, and often forming stars. Many Lynds clouds are famous star forming regions. There are already lots of observations of Lynds clouds in the Spitzer archive. We need to find something that is both as yet unobserved, but also likely to at least make a pretty picture, if not actually result in the discovery of some new baby stars.

I have looked for but have not found a biography of Lynds. Can anyone else find one?

Kitt Peak YSO Research Project

2008-10-23T21:55:34Z

Jbutchart:

<H3>Exploring A New Technique for Identifying Potential T-Tauri Stars</H3>

T-Tauri stars are very young sun-like stars in the early stages of development, and are important to astronomers. In order to better understand how our own sun developed and how our solar system came to be, we must study similar stars. T-Tauri stars are similar in mass to that of the sun, and therefore follow a similar evolutionary path. As a result, a better understanding of T-Tauri stars will lead to a better understanding of how our own sun came into being.

Stars form from collapsing clouds of gas and dust called protostar. Current models of these young stars in their early stages of formation contain a hot collapsing core surrounded by a cocoon of gas and dust. As the star matures the cloud of gas and dust slowly forms into planetary objects or is blown off into space exposing the young star.

As a result two pieces of evidence should be apparent in T-Tauri candidates. First, due to the excess gas and dust around the young star, T-Tauri stars should show significantly higher infrared emissions than older more stable stars. Second, T-Tauri stars tend to be very active and have a strong h-alpha emission line. Although, this alone would be insufficient evidence to conclude an object is indeed a T-Tauri star, it can go a long way in making such a determination.

One problem that astronomers and in particular students conducting research often run into is limited access to a spectroscope necessary to identify the h-alpha emission line in the T-tauri candidate. We believe we have a solution to this problem, and we are putting forward this proposed study to verify the validity of this new and simple technique.

<H3>METHOD</H3>

NOTE: We have identified over 100 standard stars from the Landolt: UBVRI Standards and over 50 known or likely T-Tauri candidates. Depending on the time we are given for this project, our observation plan will change. If there are two full nights made available, we have a sufficient number targets that will consume this time. However, if less time is available we can narrow our target list significantly. We estimate the minimum amount of observation time necessary for this study is eight hours. If we are fortunate enough to have this proposal accepted, a final target list will be identified and submitted prior to our observation date. The targets range between 00 – 07 hours RA, and -1d - +40 d Declination, and magnitude 10 – 18.

Stars identified as standard stars are stable and rarely change in brightness. This means they should be relatively inactive and have small h-alpha emissions when compared to more active T-Tauri stars. In addition we would expect standard stars to have significantly less infrared emission when compared to T-Tauri stars.

The 0.9 Meter combined with the R Harris, I Harris, and H-alpha filters offers the sort of size and precision instrumentation necessary for this study.

[[Image:Range.JPG]]

Our method will be to image the standard stars and the T-Tauri stars in R, I, and H-alpha. The exposure times for each object will be determined by the estimated R exposure time. The R exposure times have been calculated using the exposure calculator at http://www.noao.edu/gateway/ccdtime/ . In each image the I exposure time will always be twice the R exposure time, and the H-alpha exposure time will always be ten times the R exposure time. These exposure times should be sufficient for us to achieve a SNR of 50 or better. The data will be reduced using MaxIm DL.

For each target we will end up with an intensity value (counts) at R, I, and H-alpha. Since we will only be comparing relative brightness’s through the different filters, and the ratio for exposure times remains the same for all images, there is no need to determine magnitude using this methodology. Intensity values will be sufficient.

The following x/y scatter plot will then be generated using Microsoft Excel.

X axis – log(Icounts/Rcounts) 
Y axis – log(H-ALPHA counts/Rcounts)

Because the narrow band H-alpha filter is within the broad band R filter, very active stars (T-Tauri stars) should break away from less active stars (standard stars) in the X/Y scatter plot. In addition, because T-Tauri stars will show a significant excess in the infrared when compared to older main sequence stars, the T-Tauri stars will break away from the standard stars in the second axis as well.

If our theory is correct, the X/Y scatter plot should allow us to clearly identify T-Tauri stars from their position in the plot. We may also even be able to differentiate between class 1, 2, and 3 T-Tauri stars.

If this works, scientists and high school students without access to an astronomical grade spectroscope will have a new tool in their hands to identify potential T-Tauri stars.

Hi Cale - this is Luisa ... are you sure you're working with Hubble images? And here's another question to get you thinking. You noted that you're renaming the images to figure out "which sector of the galaxy they are in". How big are all of these images you're working with? Are they the size of, say, a quarter held at arm's length? or a pea? or a sheet of notebook paper? (bonus question: how big are Hubble images, on the same scale?)

== Meeting from 10/9/2007 at Oil City High School ==

We are going to get started monitoring our brighter T-Tauri candidates and generating light curves for them in the R and I band.

I (S. Weiser) have selecetd two targets to monitor:

SSTiau Name is 050511.5-064346, RA = 5h 5m 11.6s, DEC = -6d 43m 46.9s, Rmag = 15.3

SSTiau Name is 050517.4-063734, RA = 5h 5m 17.5s, DEC = -6d 37m 34.3s, Rmag = 16.7

Estimated exposure time - 180sec

Using http://heavens-above.com and The Sky planetarium software I've estimated we will want to be on the telescope in Perth Australia sometime between 3:00 PM and 5:00 PM EST throughout October and November. Does everyone else agree?

Using the New Mexico Sky telescope (near El Paso, Texas), we will need to be on the telescope between 6:00 AM and 7:30 AM EST. Does everyone agree?

== Meeting 10/17/07 At OCHS ==

These are the Targets I have chosen to monitor.-Nick_

SSTiau Name is 050730.1-061015, RA=05:07:30.2 DEC= -06:10:15.9

SSTiau Name is 050730.6-061059, RA=05:07:30.6 DEC= -06:10:59.7

Exposure time of 180secs, Viewing time from Oil City 2:00pm-5:00pm Est, will be using the Perth Telescope.

== Telescope Time Reserved ==

-Nick-
First attempt to take an image using Perth Failed Due to Weather. 10/17/07

== TUTORIAL QUESTIONS ==
''X-Dani-''

1) is it giong to be interactive or informational?
a) are people going to be able to "plug in" the information and it's going to spit out a light curve?
b) is it just going to be a "follow along paper" telling them how to do it step by step?

== Perth Observing results 10/22/2007 ==

From Dani ... we tried observing T-Tauri targets using the telescope. Weather looked good at 3:32 PM EST, but telescope stated "Conditions were not sufficient for Observing". Nick K also tried earlier, but got the same results.

== Observing Results 10/23/2007 ==

FROM DANI.... Tried to image at 13:31 EST and this is what it gave me...

TRY - AGAIN ..... TRY AGAIN ..... TRY AGAIN" .... this seems to happen alot. it happened to nick also when he tried to image just a few minutes before I did. is something wrong with the telescope? When I checked whether conditions it was clear and the windspeed was at 6.7, so the conditions should have been fine....... i tried again at 13:37 and it stated the same thing. pattern? okay, so it just toldme at 13:39 that the whether conditions were insuffecient or something along those lines... ''what exactly are the ideal conditions?'' [end of Dani post.]

== Perth failure ==

From Nick, today I attempted to image my targets at 13:15 est and again at 15:31est. Both times the imaging failed due to some internal problem with the Perth Telescope. I then tried at 16:20est.

From Matt H, I also attempted to image my targets at 16:00 est. At this time the imaging failed for some reason that has to do with Perth Telescope

FROMDANI... I also attempted to image and got the same results as Nick and Mattheath

RESPONSE: Dani, yes if you can post them here that would be great. Thanks, Mr. Spuck

== practice light curve .... ==

'''''........DANIELLEYEAGER.... 11/19/07 15:11EST'''''

today during 7th period mr.spuck pulled the IC2118 group aside and discussed how far we had gotten with the practice light curve and the wiki.

i am almost done with my light curve. i used the HOU [hands on universe] program to collect my data. fast and easy. However, there were only 4 constants in the images, two of which being my targets. once I create the spread sheets along with the graph, I will try to find a way to get them on here along with a step by step on how I did it.

'''''15:22EST'''''

mr.spuck saved a file into the practice folder showing 13 reference points, he also posted them on the wiki in section 17 of the discussion. i'm going to have to go back into my data and force HOU to spit out that information.

== Practice Light Curve and Loop Problem ==

..............DANIELLEYEAGER 11/30/07 1336EST

After figuring the Julian Date for the data, the light curve started to loop. By loop, I mean that the dates stacked fairly close to right above one another and circled through them forming a loop. By this loop problem, I've made the assumption that if a set of data has several points that are seconds or minutes apart, the data will loop. To solve the loop problem I averaged together the points that formed the loop and had that as my point. Doing so decreased my data points severely, but did work in achieving my desired goal.

NOTE .... when uploading pictures make sure to use EXACT title. example.. if the file name is uploaded as graph2.JPG you must type exactly, example capatalizing the JPG.

I don't really know what to do with them though. How many pictures do we have that are focused on my center? Should I start getting the data pulled together and working on my real light curve now that I am finished with my practice light curve? Or should I simply focus on mastering the wiki?

== Meeting from 10/9/2007 at Oil City High School ==

We are going to get started monitoring our brighter T-Tauri candidates and generating light curves for them in the R and I band.

I (S. Weiser) have selecetd two targets to monitor:

SSTiau Name is 050511.5-064346, RA = 5h 5m 11.6s, DEC = -6d 43m 46.9s, Rmag = 15.3

SSTiau Name is 050517.4-063734, RA = 5h 5m 17.5s, DEC = -6d 37m 34.3s, Rmag = 16.7

Estimated exposure time - 180sec

Using http://heavens-above.com and The Sky planetarium software I've estimated we will want to be on the telescope in Perth Australia sometime between 3:00 PM and 5:00 PM EST throughout October and November. Does everyone else agree?

Using the New Mexico Sky telescope (near El Paso, Texas), we will need to be on the telescope between 6:00 AM and 7:30 AM EST. Does everyone agree?

== TUTORIAL QUESTIONS ==
''X-Dani-''

1) is it giong to be interactive or informational?
a) are people going to be able to "plug in" the information and it's going to spit out a light curve?
b) is it just going to be a "follow along paper" telling them how to do it step by step?

== Perth Observing results 10/22/2007 ==

From Dani ... we tried observing T-Tauri targets using the telescope. Weather looked good at 3:32 PM EST, but telescope stated "Conditions were not sufficient for Observing". Nick K also tried earlier, but got the same results.

== Observing Results 10/23/2007 ==

FROM DANI.... Tried to image at 13:31 EST and this is what it gave me...

TRY - AGAIN ..... TRY AGAIN ..... TRY AGAIN" .... this seems to happen alot. it happened to nick also when he tried to image just a few minutes before I did. is something wrong with the telescope? When I checked whether conditions it was clear and the windspeed was at 6.7, so the conditions should have been fine....... i tried again at 13:37 and it stated the same thing. pattern? okay, so it just toldme at 13:39 that the whether conditions were insuffecient or something along those lines... ''what exactly are the ideal conditions?'' [end of Dani post.]

== Perth failure ==

From Nick, today I attempted to image my targets at 13:15 est and again at 15:31est. Both times the imaging failed due to some internal problem with the Perth Telescope. I then tried at 16:20est.

From Matt H, I also attempted to image my targets at 16:00 est. At this time the imaging failed for some reason that has to do with Perth Telescope

FROMDANI... I also attempted to image and got the same results as Nick and Mattheath

RESPONSE: Dani, yes if you can post them here that would be great. Thanks, Mr. Spuck

== practice light curve .... ==

'''''........DANIELLEYEAGER.... 11/19/07 15:11EST'''''

today during 7th period mr.spuck pulled the IC2118 group aside and discussed how far we had gotten with the practice light curve and the wiki.

i am almost done with my light curve. i used the HOU [hands on universe] program to collect my data. fast and easy. However, there were only 4 constants in the images, two of which being my targets. once I create the spread sheets along with the graph, I will try to find a way to get them on here along with a step by step on how I did it.

'''''15:22EST'''''

mr.spuck saved a file into the practice folder showing 13 reference points, he also posted them on the wiki in section 17 of the discussion. i'm going to have to go back into my data and force HOU to spit out that information.

== Practice Light Curve and Loop Problem ==

..............DANIELLEYEAGER 11/30/07 1336EST

After figuring the Julian Date for the data, the light curve started to loop. By loop, I mean that the dates stacked fairly close to right above one another and circled through them forming a loop. By this loop problem, I've made the assumption that if a set of data has several points that are seconds or minutes apart, the data will loop. To solve the loop problem I averaged together the points that formed the loop and had that as my point. Doing so decreased my data points severely, but did work in achieving my desired goal.

NOTE .... when uploading pictures make sure to use EXACT title. example.. if the file name is uploaded as graph2.JPG you must type exactly, example capatalizing the JPG.

Tried to get on perth and take some images. Telescope was in use by perth. I did go into the images we have already taken and saved some of the images titled Daniscandidates to my personal computer. I don't really know what to do with them though. How many pictures do we have that are focused on my center? Should I start getting the data pulled together and working on my real light curve now that I am finished with my practice light curve? Or should I simply focus on mastering the wiki?

== Meeting from 10/9/2007 at Oil City High School ==

We are going to get started monitoring our brighter T-Tauri candidates and generating light curves for them in the R and I band.

I (S. Weiser) have selecetd two targets to monitor:

SSTiau Name is 050511.5-064346, RA = 5h 5m 11.6s, DEC = -6d 43m 46.9s, Rmag = 15.3

SSTiau Name is 050517.4-063734, RA = 5h 5m 17.5s, DEC = -6d 37m 34.3s, Rmag = 16.7

Estimated exposure time - 180sec

Using http://heavens-above.com and The Sky planetarium software I've estimated we will want to be on the telescope in Perth Australia sometime between 3:00 PM and 5:00 PM EST throughout October and November. Does everyone else agree?

Using the New Mexico Sky telescope (near El Paso, Texas), we will need to be on the telescope between 6:00 AM and 7:30 AM EST. Does everyone agree?

== Meeting 10/17/07 At OCHS ==

These are the Targets I have chosen to monitor.-Nick_

SSTiau Name is 050730.1-061015, RA=05:07:30.2 DEC= -06:10:15.9

SSTiau Name is 050730.6-061059, RA=05:07:30.6 DEC= -06:10:59.7

Exposure time of 180secs, Viewing time from Oil City 2:00pm-5:00pm Est, will be using the Perth Telescope.

== TUTORIAL QUESTIONS ==
''X-Dani-''

1) is it giong to be interactive or informational?
a) are people going to be able to "plug in" the information and it's going to spit out a light curve?
b) is it just going to be a "follow along paper" telling them how to do it step by step?

== Perth Observing results 10/22/2007 ==

From Dani ... we tried observing T-Tauri targets using the telescope. Weather looked good at 3:32 PM EST, but telescope stated "Conditions were not sufficient for Observing". Nick K also tried earlier, but got the same results.

== Observing Results 10/23/2007 ==

FROM DANI.... Tried to image at 13:31 EST and this is what it gave me...
"Process Completed

TRY - AGAIN ..... TRY AGAIN ..... TRY AGAIN" .... this seems to happen alot. it happened to nick also when he tried to image just a few minutes before I did. is something wrong with the telescope? When I checked whether conditions it was clear and the windspeed was at 6.7, so the conditions should have been fine....... i tried again at 13:37 and it stated the same thing. pattern? okay, so it just toldme at 13:39 that the whether conditions were insuffecient or something along those lines... ''what exactly are the ideal conditions?'' [end of Dani post.]

== Perth failure ==

From Nick, today I attempted to image my targets at 13:15 est and again at 15:31est. Both times the imaging failed due to some internal problem with the Perth Telescope. I then tried at 16:20est.

From Matt H, I also attempted to image my targets at 16:00 est. At this time the imaging failed for some reason that has to do with Perth Telescope

FROMDANI... I also attempted to image and got the same results as Nick and Mattheath

== Perth ==

-Nick- Once again today Perth was unable to take images, while trying to firgure out the problem with the telescope we e-mailed Perth. They responded saying that there weather sensor had goon bad and they were having trouble with the new one.

== Failure ==

Once again today i attempted to image using perth and it is not working due to clouds and wind. Nick-11/08/08

== First Images 11/09/07 ==

Today at 1:38est I was able to get the first set of images from Perth. -Nick-

........DANIELLEYEAGER... 11/15/2007_23:57EST

What images exactly, did you collect? Only your targets or others as well?

NicK- I collect everyones field when i view, well as many as I have time to get and as long has Perth is corporateing.

== practice light curve data ==

''....DANIELLEYEAGER.. 11/15/2007_23:55EST

Would you like our practice light curves posted on here? If so, do you want our entire spread sheets as well as the graph; or just one or the other?........''

RESPONSE: Dani, yes if you can post them here that would be great. Thanks, Mr. Spuck

== practice light curve .... ==

'''''........DANIELLEYEAGER.... 11/19/07 15:11EST'''''

today during 7th period mr.spuck pulled the IC2118 group aside and discussed how far we had gotten with the practice light curve and the wiki.

i am almost done with my light curve. i used the HOU [hands on universe] program to collect my data. fast and easy. However, there were only 4 constants in the images, two of which being my targets. once I create the spread sheets along with the graph, I will try to find a way to get them on here along with a step by step on how I did it.

'''''15:22EST'''''

mr.spuck saved a file into the practice folder showing 13 reference points. i'm going to have to go back into my data and force HOU to spit out that information.

GRAPH IS IMAGE LOADED INTO PHOTOBUCKET.COM AND THEN SAVED TO THE WIKI AS GRAPH.JPG.... THIS IS THE ONLY SOLUTION I COULD COME UP WITH AS TO POSTING A PICTURE OF THE GRAPH. ANY IDEAS OR OTHER OPTIONS??

.......11/30/07 1017est......... okay, so I made a really REALLY beginner mistake and completly forgot about the fact that I had to use julian date. SOOO.. I will post a new thread with the updated information.

.....11/30/07 1042EST.............. i guess it's just a day for mistakes. i was using the file image name rather than the date and time from the header. so, i have to do the dates over again AND THEN convert into julian time.

== Practice Light Curve and Loop Problem ==

..............DANIELLEYEAGER 11/30/07 1336EST

After figuring the Julian Date for the data, the light curve started to loop. By loop, I mean that the dates stacked fairly close to right above one another and circled through them forming a loop. By this loop problem, I've made the assumption that if a set of data has several points that are seconds or minutes apart, the data will loop. To solve the loop problem I averaged together the points that formed the loop and had that as my point. Doing so decreased my data points severely, but did work in achieving my desired goal.

NOTE .... when uploading pictures make sure to use EXACT title. example.. if the file name is uploaded as graph2.JPG you must type exactly, example capatalizing the JPG.
