Color–magnitude distribution of all sources in NGC 3808 (top) and NGC 4650A (bottom). Vertical isochrone lines for ages from 0.1 to 14 Gyr are shown with solid lines for a fixed metallicity, Z = 1 Z for NGC 3808 and Z = 0.2 Z for NGC 4650A. Along the vertical lines the masses are labeled at a given age. Completeness at 50% is shown with dashed line. The arrow indicates a reddening of 0.5 mag.
