Result of partial observations focusing on the center of the cloud. PDFs are measured for the four submaps of different sizes indicated in Fig. 1. Up to a map size of 300 × 300 pixels, all high-column-density spots are included in the map. A smaller map truncates some parts of the high-density center of the map leading to a noticeable distortion of the power-law tail. The submap sizes correspond to 69%, 44%, 25%, and 11% of the original map area.
