Resource Description:
MWSC-e14a ("MWSC extension 2014a") is a catalogue of 139 new open clusters at high Galactic latitudes (|b|>20 deg) including lists of candidate members. It extends the Kharchenko et al. 'Catalog of Milky Way Star Clusters'. The target list was compiled as density enhancements found in the 2MASS point source catalogue. For confirmed clusters we determined a homogeneous set of astrophysical parameters such as membership, angular radii of the main morphological parts, proper motion, distance, reddening, age, and tidal parameters.
