Selected high-excitation line maps. The molecule, the frequency of the transition (in GHz), and the velocity range (in km s^-1) are given above each panel. The color scale ranges from 0 to 1000 K km s^-1 at 345/355 GHz, where the map size is 5′′, and from 0 to 100 K km s^-1 at 690 GHz, where the map size is 10′′. Beams are shown in the lower left, and the number in the lower right of each panel is the maximum flux in K km s^-1 (contours are  ± 20 and 50% of that value). The energy of the lower level is given in the upper left.
