Abstract
About 30 deep B and V CCD images, obtained at the 3.6 m ESO telescope, with the EFOSC in the focal reducer option, have been used to obtain color-magnitude diagrams and luminosity functions for the main sequence of the globular clusters ω Cen and NGC 3201. Two fields per cluster, at different distances from the center (25′– 30′ for ω Cen and 7.5 – 9′ for NGC 3201) were observed and separately reduced.
Based on observations obtained at the European Southern Observatory La Silla, Chile.
