Description:
Trough photometric methods we have constructed the luminosity function
for the southern open cluster NGC 2477 down to Mv≃12. We present
R-I color-magnitude diagrams and near-infrared color-color diagrams,
which allow us to separate statistically the cluster stars from the
field ones, numerous because of the galactic latitude of the cluster.
Our luminosity function (LF) reproduces some features obtained by
other authors, namely, a dip at Mv≃7, and a probable maximum at
Mv≃12. The method developed to separate cluster stars from field
stars could be of interest to other astronomical problems.
