Distribution of N₂D⁺ (3−2) emission across the core C2c1 region, (panels from left to right) Integrated intensity, peak intensity, intensity-weighted centroid velocity, and intensity-weighted velocity dispersion. Overlaid as solid black contours is the ALMA 1 mm dust continuum at 0.3″ resolution (see Fig. 1). The dashed contours in the first, third, and fourth panels are the integrated intensity, and in the second panel they are the maximum intensity. Shown on the right of the panels is the beam size, and a scale bar is shown in the lower left of all panels.
