Fig. 6

Channel map of CO 3–2 emission (red) at 5.7 km s−1 from Fig. A.1 overlaid by 13CO intensity (black) integrated from 4.9 to 5.7 km s−1. The contour levels are −3σ, 3σ, 6σ, 12σ, 24σ, and 48σ with σ = 1.8 mJy beam−1 and σ = 2.5 mJy beam−1 for the CO and the 13CO intensity, respectively. The continuum peak is marked with the yellow cross. The HPBW is shown in the bottom left corner.
