Mass-size diagram for Vela C for the unbound cores (green squares), prestellar cores (blue circles), and protostellar cores (red stars). Only the partially resolved and resolved cores are shown (with sizes 10% larger than the 11.7″ beam) to ensure acceptably accurate decon-volution results using Eq. (4). The critical Bonnor-Ebert spheres with temperatures of 6, 10, and 20 Κ are displayed by the dashed black, dashed green, and solid red lines, respectively. The dashed cyan line is the radius-mass relation for open star clusters (Marks & Kroupa 2012, Eq. (7)) and the gray envelope represents its uncertainty range. The dashed magenta line indicates an empirical relationship proposed by Kauffmann et al. (2010). The physical scale of 0.05 pc at the 11.7″ resolution is indicated by the vertical line.
