Create Observing List of Selected GAIA DR3 Objects

[aggregory]

I'm not sure how many stars makes "more than just a sample". My original query produced 250,000 targets. (I suspect that is too many.) Since my interest is comparing disk M-dwarfs (low tangential velocity) with halo M-dwarfs (high tangential velocity) I trimmed off one group of stars from each end of the velocity distribution. For high velocity, I asked for those greater than 300 km/s. This list has 408 stars. For low velocity the limit was for stars less than 2 km/s and there are 523 stars. I attached a histogram of the velocity distribution for the orginal 250,000 stars so you can have some idea why I chose these limits.

I also created an HR diagram using the calculated absolute magnitude and color. There is clear difference in the magnitudes of the two groups for early M-dwarfs. Finally, I compared the photometrically calculated metallicity of the two groups in a second histogram and the halo stars seem to have less metal and are therefore older. The HR diagram and this histogram are attached.

I'm providing this background information simply because I think it is interesting and I want to see if I can detect differences in the two groups using low resolution spectroscopy. Perhaps I won't be able to, but it will be fun trying.

So, there are two CSV files attached. Both include all of the Gaia DR3 parameters I downloaded and the RA and DEC are in the Gaia J2016.0 epoch.

Thanks and Clear Skies,
