Description:
    Trough photometric methods we have constructed the luminosity function
    for the southern open cluster NGC 2477 down to M_v_=~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 M_v_=~7, and a probable maximum at
    M_v_=~12. The method developed to separate cluster stars from field
    stars could be of interest to other astronomical problems.
