ADC_Keywords: Stars, nearby ; Stars, horizontal branch ; Space velocities Keywords: Galaxy: disk - Galaxy: halo - Galaxy: kinematics and dynamics - stars: horizontal-branch Abstract: On the basis of a recently derived color-metallicity relation and stellar parameters from the Sloan Digital Sky Survey Data Release 7 spectroscopic survey, a large sample of red horizontal-branch (RHB) candidates have been selected to serve as standard candles. The metallicity and kinematic distributions of these stars indicate that they mainly originate from the thick-disk and the halo populations. File Summary:
