Power-law indices of the N-PDFs plotted as a function of the evolutionary stages (top panel) and of the virial parameter (bottom panel) the sub-regions. The data points in the bottom panel are colored according to the sub-regions and evolutionary stages: Regions A and C are at a relatively early and quiescent stage, Region D is more evolved with an HCH II region, and Region B is the most evolved region with PDRs.
