J/other/AstBu/72.257 Homogeneous Catalog of Open Cluster Param. (Loktin+, 2017)

Updated version of the 'homogeneous catalog of open cluster parameters'. Loktin A.V., Popova M.E. <Astrophys. Bull., 72, 257-265 (2017)> =2017AstBu..72..257L (SIMBAD/NED BibCode)
ADC_Keywords: Clusters, open ; Radial velocities ; Proper motions Keywords: Galaxy: open clusters and associations: general Abstract: We present the current version of the "Homogeneous Catalog of Open Clusters Parameters", supported by our group during last decades. The catalog is created on the base of redetermination of the main parameters of clusters (colour excesses, distances from the Sun and ages) using published photometric measurements, in particular, according to the 2MASS catalog of point sources. At present, the catalog contains parameters of 1035 clusters. The catalog includes the radial velocities data for 496 open clusters. All clusters of the catalog have estimates of the components of proper motion. Description: Fundamental parameters of 1052 open clusters of the Galaxy are redetermined on the base of published photometry of stars. File Summary:
