Catalog of red clump candidates in Tycho-2

Abstract

We present the technique we used to compile a catalog of about 61 000 local stars brighter than K_s = 8.2^m which were identified as most likely red clump candidates on the basis of their reduced proper motions in the K_s band. The catalog was compiled from the combined Tycho-2 and 2MASS data for the stars with color indices J-K_s ranging from 0.5^m to 0.8^m. It includes the equatorial coordinates, the proper motions, the magnitudes B_T, V_T, J, H, and K_s, and the probabilities for the stars to be red clump giants.
