Descripción
A photometric analysis is conducted of the open cluster NGC 7044, on the
basis of UBVR CCD observations of 896 stars in the cluster field.
Reddening and metallicity estimates are highly dependent on whether
reddening slopes and absorption coefficients vary with spectral type.
The color-magnitude diagram obtained is compared with selected sets of
isochones, based on evolutionary models computed with and without
consideration of convective overshooting from the stellar core during
the H and He phases of core burning. Better general agreement is
obtained between predicted and observed features of the color-magnitude
diagram with overshooting models.
