Abstract:
We present UBVRI photometry of the open cluster NGC 2422 (age∼108yr)
down to a limiting magnitude V≃19. 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.
