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.
