Position-velocity (p-v) maps of HCN and HCO+. The cuts along the axes of rotation are shown by the dashed lines in Fig. 8. Contour steps of the (1 − 0) maps go from 0.9 mJy beam−1 (3σ) to 7.9 mJy beam−1 with steps of 1 mJy beam−1. For the (3 − 2) maps, contours go from 3.9 mJy beam−1 (3σ) to 59 mJy beam−1 with steps of 5 mJy beam−1.
