Dereddened (V,V − I) color–magnitude diagram. Symbols as in Figs. 5 and 10. Also shown are the ZAMS for lower MS stars (blue), a Geneva 3-Myr isochrone for massive stars (red), and selected isochrones (dashed black) and evolutionary tracks (solid black) for lower mass stars from Siess et al. (2000); these latter are labeled with stellar mass in solar units. The A0 and earlier type stars have been projected to the MS (along the combined foreground + cluster reddening vector, as shown), since they lack a detailed classification.
