V vs. V − I diagram of all the objects (dots) with errors in V − I smaller than 0.1. Filled circles are the diskless candidate cluster members, while squares indicate those with E(B − V) between 0.5 and 0.7, according to Fig. 7. Solid line is the solar metallicity ZAMS of Siess et al. (2000) at a distance of 3.6 kpc and reddening E(B − V) = 0.4. Dashed lines indicate the 1.5 Myr Marigo et al. (2008) isochrone of solar metallicity for masses larger than 2 M_⊙ at 3.6 kpc and for E(B − V) = 0.5, 0.6 and 0.7. The reddening vector obtained using the Munari & Carraro (1996) reddening laws is also shown.
