Dust colour temperature (TC, top) and the H2 column density (N(H2), bottom) maps of H-MM1 as derived from Herschel/SPIRE maps at 250, 350, and 500 μm. The distribution of the 850 μm emission observed with SCUBA-2 is indicated with black contours on the N(H2) map. The contour levels are 10 to 50 by 10 MJy sr-1. The column density maximum is marked with a plus sign. The present observations were pointed towards this position, with coordinates RA , Dec. −24°33′33″ (J2000). The larger circle in the bottom right represents the resolution of the N(H2) and TC maps (~ 40″). The 14′′ resolution of the SCUBA-2 850 μm map is indicated with the smaller circle. The lowest 850 μm contour (10 MJy sr-1) approximately coincides with the N(H2) = 2 × 1022 cm-2 contour.
