V vs. U − B diagram from the Massey et al. (1995) and Sharma et al. (2007) photometry (upper panels) and V vs. V − I diagram of all the objects with errors in V − I smaller than 0.1 and located in the regions with A_V > 3.8 (bottom panels). Filled circles are the diskless candidate cluster members; squares are those with 0.5 < E(B − V) < 0.7; solid line is the 3.0 Myr isochrone of solar metallicity using E(B − V) = 0.6, while dashed line is the solar metallicity ZAMS of Siess et al. (2000) using E(B − V) = 0.4; both are drawn assuming a distance of 3.6 kpc. The reddening vector obtained using the Munari & Carraro (1996) reddening laws is also shown.
