CCD photometry of young MC clusters I: NGC 2172
Abstract
We present a new CCD photometry for the young LMC cluster NGC 2172, giving B,V,I magnitudes for more than 600 stars within 70'' from the cluster center, down to -approximately- V= 21 mag. After correction for completeness and field stars contamination, we discuss the cluster HR diagram and the MS luminosity function in the light of current evolutionary theories and in connection with the problem of cluster age. Based on observations collected at the European Southern Observatory, La Silla, Chile
