| − | 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.

| − | ..............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.

| |
| − |
| |
| − | 1. Did the two of you use all the same reference stars?
| |
| − |
| |
| − | 2. Did the two of you use the same software to get the brightness values for your reference stars and YSO candidates?
| |
| − |
| |
| − | Also, I'd like to se you modify your graph a bit. Label the Y axis more clearly (don't just say ratio ... ratio of what?). Also, turn the julian dates (ie. like I had Dani do hers). And use the scatter plot with the line connecting the data points. Also correct your spelling error in the graph title. Thanks.
| |

| |
| − | --[[User:Nicholas|Nicholas]] 10:36, 6 December 2007 (PST) Well Mr. Spuck Dani walked me through what to do with the Light Curve so it would be understandable why our light curves would be similar. [end]

The graphs show two different candidates rather than two different filters for the same candidate. Both light curves need redone, focusing on one candidate in both the I and the R filters. Each graph needs to show the I and R light curve for one candidate. [end]

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?
--Spuck 11:18, 4 December 2007 (PST) Dani, you're doing a great job with the Wiki. Unfortunately the Perth Telescope is down for now. I just found out today that the RA motor went bad in the mount. I will post more news as I get it. We will probably have to start using New Mexico Skies telescope for our observations. This means being up at 2:00 AM EST ... any volunteers? For now, why don't you focus on working with the rest of the team ... bringing them up to spped on how to access and use the Wiki, as well as working through the Wiki to see what we should focus on in our AAS Poster.

While trying to save over my images, when clicked, some files opened to a page showing the picture directly, where as others had a prompt coming up asking whether I wanted to find the image or save the image. Why?
--Spuck 11:18, 4 December 2007 (PST) Dani, I'm not sure. WHy don't you show me this when you have a chance. Thanks.

Today, stayed after with Alexis, Danielle, Cale, and Alix in Mr. Spuck's room. Took notes on basics of things for the Austin trip. Parents signed the permission slip and are pleased with the trip. Mom's meeting with Mr. Spuck went well, obviously.
2:40-5:10, worked on galaxy research.
Tomorrow, doing notes on the book Mr. Spuck gave me.
I officially have my hours as of today. :)
--Spuck 11:29, 4 December 2007 (PST) Jennifer, I'll need to see the log of your hours sometime before friday. Also, why don't you type up the notes from our discussion and get them posted on to the galaxy classification board. You can make the graphics in paint, or draw and scan them in, or use a digital camera to take pics of your notes and upload the graphics. Either way is fine with me.

Jennifer, again, good job on posting, but please post in the Galaxy section, if you need a refresher on how to get to it, from the main page go to Future Research Projects and then from there Galaxy then discussion. I beleive that is the route.
--Spuck 11:25, 4 December 2007 (PST) FYI ... here is the link again to the Go to the discussion page off of the Galaxy Clasification Page.

UPDATE IN HOW TO POST PLEASE READ
--NicholasJamesKelley 10:13, 11 December 2007 (PST) Perth is still down and therefore we have decided to try and make the switch to New Mexico Skies to finish collecting data to get better light curves.
