Fig. 12
Comparison of the position velocity map along the Δα axis and averaged over a region of ~2.5′′. The colour scale shows the CO (3–2) emission, which is heavily affected by missing spacings and self-absorption at the source vlsr. The dark grey contours show the CH3OH vt = 1, white contours show HC3N (37–37) (left panel) and HC3N v7 = 1 (right panel) transitions.
