The CO environment of N49: the 870 μm contour levels (0.1, 0.2, 0.5, 1.0, 1.5, and 2.0 Jy/beam) are superimposed on the Galactic Ring Survey ¹³CO (1 − 0) emission (Jackson et al. 2006) integrated over all velocities (left), on the B&W ¹²CO (3 − 2) emission integrated over the velocity (middle), and on the B&W ¹²CO (3 − 2) peak intensity map (right). The dense dust condensation #1 is almost absent from the CO peak intensity map, whereas condensation #2, associated with the UC H ii region, is bright (presumably a temperature effect). The CO (1 − 0) and (3 − 2) emissions integrated over velocity are more similar to the 870 μm emission. However, the dust condensation #1 is much brighter at 870 μm than it is in CO.
