Gaia Sprint

BHB (+ blue straggler) catalogue with distances and proper motions (updated using Sergey's database), and BHB probabilities using random forest classifier trained on SDSS spectroscopic sample (labelled using their log g). TGAS+RAVE-on with a few cuts and angles+frequencies computed. Only appropriate for investigating large scale trends because I have not sampled from the error ellipsoids for each target. Also, I used 1/parallax (sorry), but will update soon using better distance estimates. I can provide the SQL queries I used to get these samples. NB both catalogs will probably be changed throughout the course of the week so check with me before you finalise results!
