Left and right panels show, respectively, the zero-moment maps of the CH3OH (E2) ﹩{6}_{-\mathrm{2,5}}\to {7}_{-\mathrm{1,7}}﹩ and ﹩{6}_{\mathrm{1,6}}\to {5}_{\mathrm{0,5}}﹩ (vt = 1) transitions. Red crosses and numbers show the position of continuum 3 mm sources as defined in Paper I. The upper-energy levels of these two transitions are 74.7 and 340.1 K, respectively.
