Top panel: color scale and contours show the P − V diagram of the CO(6–5) transition computed along the cut indicated by the white arrow in the bottom panel. Offset positions increase along the direction of the arrow shown in the bottom panel. Bottom panel: distribution of the integrated intensity of the ¹³CO(6–5) transition towards the hot core G327.3–0.6. Solid contours show the continuum emission at 350 μm (Wyrowski et al., in prep.) from 3σ in steps of 10σ (σ ~ 3 Jy/beam). Symbols are as in Fig. 2.
