Top left to bottom right: logarithmic distributions of the clump mass (﹩{M}_{\mathrm{clump}}/{M}_{\odot }﹩), bolometric luminosity (﹩{L}_{\mathrm{bol}}/{L}_{\odot }﹩), peak H₂ column density (﹩{N}_{{{\rm{H}}}_{2}}/{\mathrm{cm}}^{2}﹩), and luminosity-to-mass ratio (﹩{L}_{\mathrm{bol}}/{M}_{\mathrm{clump}}({L}_{\odot }/{M}_{\odot })﹩) for the 225 outflow clumps (red dashed lines) compared to the 100 clumps without outflows (blue dashed lines). The bin sizes are 0.2, 0.25, 0.1, and 0.2 dex from top left to bottom right. The ﹩L/M﹩ ratio is a well-identified indicator of clump evolution with larger values for more evolved clumps, and the peak H₂ column density shows a very strong positive correlation with the fraction of clumps associated with MSF (Urquhart et al. 2018).
