Panel A) histogram of the mass distributions for the ¹³CO clumps (solid red lines) and 1.2 mm clumps (solid blue lines). The dashed lines indicate the fits with α = 1.9 ± 0.1 for ¹³CO clumps and α = 1.9 ± 0.2 for 1.2 mm clumps. Panel B) normalized cumulative mass functions for the ¹³CO clumps (solid red lines) and 1.2 mm clumps (solid blue lines). The dashed lines indicate the fits with α = 1.8 ± 0.1 for ¹³CO clumps and α = 1.8 ± 0.2 for 1.2 mm clumps.
