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><source
