Description:
We present the catalogue of 60910 local stars brighter than Ks=8.2mag,
which were assigned to be the most probable Red Clump candidates from
Ks-band reduced proper motions. The catalogue is the result of
analysis of combined Tycho-2 and 2MASS data selected in (J-Ks)
interval from 0.5 to 0.8mag. It includes Tycho-2, Hipparcos and 2MASS
numbers, equatorial coordinates J2000.0, proper motions and their
standard errors, Tycho-2 B and V magnitudes, 2MASS J, H, Ks
magnitudes, and Red Clump probabilities. All astrometric data were
extracted from the Tycho-2 main catalogue; photometric data were
extracted from the Tycho-2 and 2MASS catalogues. Red Clump
probabilities were calculated by means of maximum-likelihood method
based on Ks-band reduced proper motions. The catalogue provides data
listed in order of right ascension increasing. About 85% of the sample
stars are proved may be actual Red Clump giants as resulted from both
Ks-band absolute magnitude analysis and the MK spectral
classification.
