H₂ column density map of the Corona Australis molecular cloud at 18.2″ angular resolution, derived from the Herschel data using the method discussed in Sect. 4.1. The grey filled circleswith white outlines, and filled green stars with back outlines, are the locations of the 163 starless cores and 14 protostellar cores identified using Herschel images with getsources (see Sect. 5). The black star towards the west is the location of the Coronet cluster, containing the well-studied variable star R CrA. There are 62 faint sources, shown by yellow downward triangles and stars, which are contained within the catalogue, but excluded from the scientific discussion on the ground that they are likely to be extragalactic (see Appendix B for details). The relative orientation of the galactic coordinate axes is indicated at the lower right.
