Left panel: Hα flux vs. T_eff. Right panel: vs. T_eff. In both panels the Class II and Class III objects are distinguished as in previous figures. The objects that can be considered accretors, according to the White & Basri (2003) criterion, are highlighted in blue in the upper half of the symbol. Data for YSOs with transitional disks (TD) are enclosed in open green diamonds. In both panels, the dashed straight line is the boundary between chromospheric emission and accretion as derived by Frasca et al. (2015) for the Gamma Vel and Cha I SFRs. The downward arrow in each panel indicates the only upper limit (2MASS J16085373-3914367).
