Revision as of 23:24, 1 July 2014
This page is similar in concept to the summer visit pages for my prior teams (Working with the C-CWEL data; Working with the C-WAYS data page; Working with the BRCs; Working with CG4+SA101 page; Working with L1688) HOWEVER, this page was developed and updated specifically for the 2014 HG-WELS team visit. Because this team has a very different science goal, it is very different, at least in places, than these other pages.
Please note: NONE of these pages are meant to be used without applying your brain! They are NOT cookbooks! This is presented as a linear progression because of the nature of this page, but we have already done some things "out of order", and moreover, chances are excellent that you will go back and redo different pieces of this at different stages of your work.

Assembling our initial catalog
DONE but kept here for reference because it is easy to forget.
We assembled our catalog in the spring from basically three sources:
- de la Reza's published catalog - biased towards sources bright in the IR
- Carlberg's published catalog - much less biased set of giants assembled without regard to IR or Li, spanning range of vsini
- Carlberg's private communication set of objects mentioned in the literature as Li rich (some of which subsequently vanished from de la reza's papers)
We have a list of 196 unique objects that we assembled, keeping track of where the source was listed. Sometimes it is listed in more than one of those three places.
Big picture goal: Understand which sources have been studied for these three samples, and what has been measured for them.
Relevant links:
- How can I find out what scientists already know about a particular astronomy topic or object?
- I'm ready to go on to the "Advanced" Literature Searching section
Assembling other data from large catalogs
Big picture goal: We are ultimately trying to get an understanding of whether or not these stars have excesses. It will further that goal if we accumulate as much data as we can from a variety of sources.
Relevant links:
- How can I get data from other wavelengths to compare with infrared data from Spitzer? - though this focuses more on imaging. We need photometry.
- FinderChart at IRSA
- IRSA in general
- Catalog search at IRSA IMPORTANT AND NEW TO YOU
- Resolution - spatial resolution matters!
- HG-WELS Resolution Worksheet - the worksheet we did in the Spring
- Vizier
FLESH THIS OUT
Checking that the coordinates and photometry make sense, part 1 - image inspection
DONE at least a first pass.
Big picture goal: Just because the computer says it, does not make it right. Always check to make sure that the computer is correct. (AKA "count your change.")
More specific shorter term goals: Investigate the images for each source. Do we have the coordinates right? Is it just one point source? This is one of the major goals of our work, to determine if there is "source confusion" at these locations.

FLESH THIS OUT
you may need to loop back to the prior step after doing this.
Checking that the coordinates and photometry make sense, part 2 - making some SEDs
DONE because Luisa felt bad that some stuff wasn't working and then she found a bug and then decided to just do it. But
