Corrected M_compact (column marked “c” in Table 4) versus . The corrected compact mass of Per-emb 16 is negative, and the uncorrected mass has therefore been used for this object. Green symbols represent sources that are identified as disk candidates in resolved continuum surveys (cf. Table 4). Triangular symbols represent sources that are associated with a companion protostar at a projected distance <0.8′′ (Tobin et al. 2016; also see Fig. 2). Round symbols represent sources with no close companion.
