We present new UBVRI photometric catalog for eight open star clusters, i.e. for NGC 6793, NGC 6800, NGC 1027, NGC 2129, NGC 1502, NGC 6531, King 12 and NGC 2467. Many of these clusters are poorly studied. The data is collected from 104-cm Sampurnanand Optical Telescope, ARIES Nainital, using 2kx2k CCD which covers about 13x13 arcmin square field on sky. The data reduction is done in homogeneous manner and a global catalog of all the stars in the observed field have been generated. We are able to reach down to ~ 21 mag in V band. Variability data as well as Hα have also been taken for few clusters. The study aims to determine member stars of clusters using the present catalog as well as the archival astrometric catalog. This homogeneous set of data will help us to determine the fundamental parameters (distances and ages) and the mass function of clusters. |
