Oil City Discussion

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

--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.

--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:

--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:

--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):


--skennedy 5:02, 23 October 2008 (PDT) This is my list of interesting objects in LDN 425 that I found in several different color composites.


--Skennedy 14:28, 23 October 2008 (PDT) Mr. Spuck and I are going to look further into this previously done research to see what targets have already been discovered.

Lee and Myers (1999, ApJS, 123, 233) find a YSO here (1950 coords: 17 44 15.4 −04 34 07) IRAS source 17442−0433 Connelley et al (2007 AJ 133, 1528) find a new NIR reflection nebula here, suggestive that a YSO is illuminating the nebula, and that we will see something pretty at IRAC bands. the part that is the center of the coordinates given by lynds (center of image at left) seems offset from the darkest part as seen in POSS. X's in graphic at left are the IRAS point sources in this region; the northernmost one is the one listed in the literature. there is not much to the dark cloud north of the image region shown at left. I'm taking as the center 17:46:55 -04:36:25; see second graphic at left.

--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.


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.

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

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.
