star_cats

Code to access star catalogue data. Thus far, this means UCACs 2, 3, and 4; URAT1; Dave Tholen's Gaia32 (compressed, re-sorted Gaia DR1 and, later, DR2 with just the bits needed for asteroid astrometry); and for CMC-14 and CMC-15.

Code for other catalogues will be added as I get around to it (I have code for UCAC1, Ax.0, Bx.0, GSC-1.x, and more... just not posted yet; I've focussed on catalogues people are most likely to use.)
