Scientific paper

The catalogue is a result of studies of wide neighborhoods of 513 open clusters and 7 compact associations carried out in high precision homogeneous all sky catalogue ASCC-2.5 (Kharchenko, 2001, Cat. ). On the basis of data on about 33000 possible members (including about 10000 most probable ones) and homogeneous methods of cluster parameter determination the angular sizes of cluster cores and coronae, cluster heliocentric distances, mean proper motions, mean radial velocities and ages were established and collected in the COCD. These include cluster distances for 200 clusters, average cluster radial velocities for 94 clusters, and cluster ages for 195 clusters derived for the first time. Clusters in the catalogue are sorted by right ascension J2000 order.
The Open Cluster Diagrams Atlas (OCDA) presents a set of open cluster diagrams used for the determination of parameters of 513 open clusters and 7 compact associations, and is intended to illustrate the quality of the constructed cluster membership (Kharchenko et al., 2004, Cat. ), and the accuracy of the derived cluster parameters (this paper). Every diagram presents relation between various stellar data from all sky catalogue ASCC-2.5 (Kharchenko 2001, Cat. ) in area of the specific cluster. There are five diagrams provided for every cluster in the Atlas: the area map, the density profile, the vector point diagram, the magnitude equation diagram, and the color-magnitude diagram. The OCDA consists of 520 PostScript plots stored as gzipped files (i.e. one file per cluster).
(4 data files).
