Channel maps of the six brightest molecular lines are shown: C¹⁸O 2−1, ¹³CO 2−1, ¹²CO 2−1, HCN 3−2, HCO⁺ 3− 2, and SO 5₆−4₅ (top to bottom). Each panel shows the line intensities integrated over six channels (left to right) and after clipping pixels with intensities <3σ. The grey box in the first row indicates the average velocity of the six channels. The color scale for molecular line is shown at the right hand side. The dust continuum emission of the aggregated observations is plotted linearly as black contours from 5σ to maximum intensity. Beam sizes for each line can be found in Table 2.
