Close-up with details of the submillimetre cores with a S/N ≥ 5. Colours represent the Herschel PACS map at 160 μm superposed onto the background. Contours represent LABOCA emission at 870 μm. Lower contour represents 3σ emission, with an increment of 1σ between contours for all cores, except for the one corresponding to cores K (DK Cha), L, and M, with contours at 3σ, 5σ, 7σ, 9σ, 12σ, 15σ, 20σ, 30σ, 40σ, 50σ, 60σ, 90σ, 120σ, 170σ, 220σ, 270σ, 350σ, and cores D (IRAS 12500-7658) and E, with contours at 3σ, 5σ, 7σ, 9σ, 12σ, 15σ, and 20σ. See different range of values of root mean square (rms) in Table 2.
