These data are used to derive the Luminosity and Mass Functions and to study the cluster spatial distribution. By considering the color-magnitude diagram data and adopting a representative cluster main sequence, we obtained a list of candidate cluster members based on a photometric criterion. Description: The data used in this paper are CCD images in the UBVRI pass-bands collected at the 0.9-m telescope of the Cerro Tololo Inter-American Observatory (CTIO) on January 30, 1997.
