Top: color scale and contours show the P-V diagram of the CO(6–5) transition computed along a vertical cut passing through the outflow a) and the hot core position b). Bottom: color scale and contours show the P-V diagram of the 2₀₂−1₁₁ H₂O line computed along a vertical cut passing through the outflow c) and the hot core position d). The cut through the outflow position is from to , the cut through the hot core from to . Offset positions increase along the direction of the cuts. Contours are from 3σ in steps of 3σ for H₂O, and in steps of 5σ for CO.
