From left to right: zeroth-, first-, and second-moment map of CS 3–2 observed with NOEMA. The first- and second-moment maps were computed using a 3σ threshold to avoid noisy channels. Contours in the zeroth- and second-moment maps are shown for 0.25, 0.5, 0.75, and 0.9 of the integrated intensity map peak. The dashed white ellipse in the zeroth-moment map shows the area used to compute the integrated spectrum shown in Fig. 2.
