Fig. 5


Stacked PV diagrams of HCN 1–0, 2–1, and 3–2; and HCO+ 1–0 and 2–1 in the combined data (contours start at 2σ, and continue at 2σ intervals). The HCO+ 3–2 line is not included owing to the HCN 3–2 v2 = 1 blend at 400 km s-1. In the PV diagrams, the positions of the HCO+ outflow features identified in the stacked PV diagrams are indicated by plus signs and the HCN features are indicated by crosses. In the HCN PV diagrams, the HCN markers are white and the HCO+ markers are red. In the HCO+ PV diagrams, the HCO+ markers are white and the HCN markers are red.
