RE: Create Observing List of Selected GAIA DR3 Objects - PMSchu - 2024-05-05
Hi Antone,
I downloaded your 2 .csv files and have some questions. What are the units on the RA column, just degrees? To convert to Hours, I just divide by 15°/hr, correct? What are the units on the proper motion columns (P, T & U), milliarcseconds/year (mas/yr)?
It looks like you also have columns for the Green-Red and Blue-Red magnitudes. Would it be worthwile to calculate a Blue-Green magnitude column to approximate the B-V color Index that SkyTools can search on in the stellar data?
As a test I did a Database Power Search (DBPS) for stars brighter than 15 magnitude and B-V>1 (red stars) with proper motions greater than 5"/year. The Observing List (OL) is attached.
I've also extracted a few of the brighter stars from your high_v_tan file, but haven't done anything with them yet.

Antone,
I got called away last weekend and wasn't able to look at your data. I'll try again this weekend. Do you have any more recent lists for me to look at?
