IRDC310.39-0.30. Left: the image is the PACS 100 μm with SPIRE 350 μm contours overplotted. The white contour levels begin at 14 Jy beam^-1 and increase in steps of 5 Jy beam^-1. The blue circles are PACS cores identified in Ragan et al. (2012b), and green circles are candidate 70 μm-dark cores. A circle is filled if it is recovered as a “leaf” with SABOCA, and it is left open if it is not. Cyan crosses are the positions of all dendrogram leaves. Right: SABOCA 350 μm image is plotted in grayscale with red contours showing the “leaf” structures identified with dendrogram and green contours show lower-level structures (“branches”) in emission, if any. The scalebar is in units of Jy beam^-1. See Sect. 3 for details.
