Luminosity and Mass Function of the Galactic open cluster NGC 2422
2003
Astronomy and Astrophysics
We present UBVRI photometry of the open cluster NGC 2422 (age ∼ 10^8 yr) 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. Using a reference field region and an iterative procedure, a correction for contaminating field
