File:CandidateResearch brc27 dcs 27Aug.xlsx

Clarification on the referenced excel file that I sent out;

Column B: Since one of our tasks was to determine which of these objects have been previously identified, I went to Harvard's site for Simbad

http://vizier.cfa.harvard.edu/viz-bin/nph-aladin.pl

(be sure you select the Aladin applet for the US, or it will take you to France)

For each of the candidates, I looked to see if there was any kind of identification. (You will notice that so many things are labeled, it's actually surprising to find an object that does not have a one) Be sure to scroll down the the bottom of the screen to see if they have actual names; many of them are labeled Ogura.

If it says YSO, it was labeled as such on Simbad , which means somebody identified it at some point in the past... Query: That means we are confirming it?

When I could find someone to attribute a YSO to, I credited them. (see column AA) Candidates 4, 5, 11 & 28 are are not labelled on the diagram but are Ogura 3, 4, 7 & 19. Since they are in the literature, I'm not sure why they are not labeled image.

Objects that were cited as A's or B's, I took at face value (6,7, 10, 14, & 27). I think I understand how 27 is a blob in IRAC, but a faint point source in JHK, but why is it brighter in its R magnitude than its V magnitude? The U & B magnitudes are dimmer than the V, and I would not expect that from a B. (does that make sense?)

Candidates 29, 30, & 31 are still interesting.


Column I: anything coded yellow is something I thought was a star before I started digging. What I based that on was whether or not we had a V magnitude farther over on the table (which just happens to also be column V). I revised those opinions based on what I found in Simbad and what is in column J.

Column J: Gator DSS & 2MASS/ This brought up 5 images from DSS (information at the bottom of the column) and JHK, so I was comparing the way each object looked for the different bands.

Going through it one more time, some of my thoughts have changed, and so has the file. I'll post it to the wiki (if I can).

Is #1 really a star? --Sartore 13:31, 27 August 2011 (PDT)
