Kinematics of Metal-poor Stars in the Galaxy. II. Proper Motions for a Large Nonkinematically Selected Sample

We present a revised catalog of 2106 Galactic stars, selected withoutkinematic bias, and with available radial velocities, distance estimates, andmetal abundances in the range 0.0 <= [Fe/H] <= -4.0. This update of the Beersand Sommer-Larsen (1995) catalog includes newly-derived homogeneous photometricdistance estimates, revised radial velocities for a number of stars withrecently obtained high-resolution spectra, and refined metallicities for starsoriginally identified in the HK objective-prism survey (which account fornearly half of the catalog) based on a recent re-calibration. A subset of 1258stars in this catalog have available proper motions, based on measurementsobtained with the Hipparcos astrometry satellite, or taken from the updatedAstrographic Catalogue (AC 2000; second epoch positions from either the HubbleSpace Telescope Guide Star Catalog or the Tycho Catalogue), the Yale/San JuanSouthern Proper Motion (SPM) Catalog 2.0, and the Lick Northern Proper Motion(NPM1) Catalog. Our present catalog includes 388 RR Lyrae variables (182 ofwhich are newly added), 38 variables of other types, and 1680 non-variables,with distances in the range 0.1 to 40 kpc.
