Astrometric Study of Galactic Clusters. I. NGC 3532

Abstract: Astrometric study of galactic clusters using UCAC2 catalog containing proper motion data is described. Kinematical analysis is applied to determine cluster membership. The near infrared photometric data of the same catalog is used to derive physical parameters of the cluster. In the present study the case for NGC 3532 is given. An isochrones fitting to the color-magnitude diagram gives the age of cluster in log t = 8.85 and the distance of  515 ± 41 pc with infrared reddening in J filter of  0.043 ± 0.017 mag. Our results are in good agreement with  results of previous studies.
