Cluster membership probability determined using the model (upper panel) and the VISTA CF (lower panel) as a CF in the process of decontamination. The solid black line represents the 1 Myr isochrone combined from the PARSEC and BT-Settl models at 1 M_⊙ (Bressan et al. 2012; Chen et al. 2014; Baraffe et al. 2015). The reddening vector of A_V=3 mag is shown. The dashed grey line represents the 90% completeness limit, the dotted grey line the 50% completeness limit, and the solid grey line the 20% completeness limit.
