Cumulative distributions of the physical properties for the total 2052 clumps, the 1192 outflow clumps, and the 860 non-outflow clumps. Top left (a,b,c) to bottom right (d,e,f): cumulative distributions of clump mass (M_clump (M_⊙)), bolometric luminosity of central objects (L_bol∕L_⊙), luminosity-to-mass ratio (L_bol∕M_clump (L_⊙∕M_⊙)), the peak H₂ column density (peak N(H₂) cm⁻²), the mean mass surface density (Σ (M_⊙ pc⁻²)), and the mean volume H₂ density (n(H₂) (cm⁻³)) of the total 2052 clumps (black lines), the 1192 outflow clumps (magenta lines), and the 860 non-outflow clumps (green lines). We present the median values of the three samples in vertical lines, and p-values of K–S testsbetween the outflow sample and the non-outflow in each plot.
