Division of the Corona Australis molecular cloud into significant “clumps” of emission that are prominent in all emission maps and the column density maps. The hollow, grey-filled, and colour-filled circles are starless cores, candidate prestellar cores, and robust prestellar cores, respectively. The following colours are used for the symbols: red for CrA-A, brown for CrA-B, green for CrA-C, orange for CrA-D, dark blue for CrA-E, cyan for CrA-F, sea green for CrA-G, and magenta for CrA-H. The green stars represent YSO and protostellar candidates. Cores with no defined subregion are black. The contour levels start from 3σ ~ 1021 N(H2) cm−2, and increase in levels of 1.5 times the previous level. The black bars towards the lower right of each cut-out show a 0.5 pc transverse distance at the adopted distance of CrA.
