Similar to Fig. 5. In this figure, we plot the confirmed binary or multiple sources inthe left panel, and plot the rest of the sources in the right panel. We exclude RNO 1B, RNO 1C, and HBC 722 which are located in condensed stellar cluster forming regions (Fig. 1; see also Dunham et al. 2012). Purple, light blue, red, and green dotted lines present the M_* > 1.3 M_⊙ Class II objects in the Taurus, Lupus, Chameleon I, and Upper Sco regions, respectively (quoted from Pascucci et al. 2016; the original observations can be found in Andrews et al. 2013; Carpenter et al. 2014; Ansdell et al. 2016; Barenfeld et al. 2016; and Pascucci et al. 2016).
