Integrated line maps. Above each panel, the molecule, the frequency of the transition (in GHz), and the velocity range (in km s^-1) are given. The map size is either 5, 10, or 15′′, as written in the map (tick spaces are 1′′, centered on RA 18:08:38.236, Dec –19:51:50.25). 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 (the contours are  ± 20 and 50% of that value). The color scale ranges from the minimum to the maximum value. The energy of the lower level is given in the upper left.
