Overlay of CO(2–1) p − v plots (contours in Jy beam⁻¹-units) along the average major axis (upper panel: PA = 291° = 180° +111°; where we adopt the orientation of the receding side of the major axis) and average minor axis (lower panel: PA = 21°) on the corresponding synthetic p − v plots (in logarithmic color scale) generated by ^3DBarolo for the best-fit model described in Sect. 7. In our convention Δx-offsets are > 0 to the SE and Δy-offsets are > 0 to the NE. Contour levels in the upper panel are 1.3%, 3%, 5%, and then 10%–90% in steps of 10% of the peak value = 23.1 mJy beam⁻¹. Contour levels in the lower panel are 2.7%, 5%, and then 10%–90% in steps of 10% of the peak value = 9.1 mJy beam⁻¹. The regions identified as OUT-N and OUT-S in the lower panel correspond to the crossings of the AGN-wind working surface with the molecular gas at the N and S extremes of the CND.
