... Since GCVS IV, there was no new GCVS edition. ... Main reasons for the automatic-survey new variables remaining outside the GCVS for a long time:  different level of detail of the classification systems, no perfect software for automatic classification available;  individual approach to each star that was always used in the GCVS cannot be applied any longer, but the experience of automatically- updated catalogs evidences for the number of errors ...

... Structure of Data . ... Catalog . ... In SAI OCL Catalog, we introduce our work on investigation of the Milky Way system of open star clusters. The main goal of our study is a search for new clusters using huge surveys. 168 new clusters have been already discovered by us using J,H,Ks data from 2MASS point source catalog. ... For 141 new clusters, we found their physical parameters using J,H,Ks data from 2MASS catalog and, for a number of clusters, our UBVRI CCD observational magnitudes. ...
