Extinction-corrected ﹩{{(V-{{I}_{C}})}_{0}}﹩, ﹩{{V}_{0}}﹩ color–magnitude diagram for the Hα emission stars and X-ray sources with available optical photometry. Stars of known spectral type have been corrected individually for reddening using the intrinsic colors of 5–30 Myr pre-main sequence stars from Pecaut & Mamajek (2013). Sources without spectral type information are plotted using the mean extinction derived for the cluster ﹩{{A}_{V}}=1.79﹩ mag. Superposed are the 0.5, 1.0, 3.0, and 10 Myr isochrones and the 0.3, 0.5, and 1.0 M﹩_{\odot }﹩ evolutionary tracks of the solar metallicity models of Siess et al. (2000), assuming a distance of 1150 pc (Straižys et al. 2014).
