S.P. Rybka & A.I. Yatsenko Catalogue of 2.2 million candidate Red Clump giants selected from the 2MASS down to Ks=11 magnitude at galacic latidudes 5<|b|<30 degrees.

Description: We present the catalogue RCG2M_1 of about 2.2 million stars brighter than Ks=11 mag at galactic latitudes 5<|b|<30 deg, which were selected as the most probable Red Clump giants on the 2MASS color-magnitude diagrams.The catalogue includes 2MASS numbers, equatorial coordinates, 2MASS J,H,Ks magnitudes and their errors, and Red Clump probability. Red Clump probability was calculated by means of maximum-likelihood method based on common J-Ks color distribution of Red Clump and Giant Branch stars. About 84% of the selected stars are proved to be Red Clump members from the MK spectral classification. References: Rybka S.P., Yatsenko A.I.
