In the massive star-forming region IRAS 21078+5211, a highly fragmented cluster (0. 1~pc in size) of molecular cores is observed, located at the density peak of an elongated (1~pc in size) molecular cloud.

The observed DGMF is a metric for the instantaneous clump-formation efficiency (CFE) in the molecular gas and a two-dimensional power-spectrum analysis of the DGMF reveals a break in slope at the approximate size scale of molecular clouds.
