CO J = 2–1 spectra from the merged, obs-17 and obs-19 data cubes. The spectra are smoothed to a velocity resolution of 3 km s−1 and extracted from the area defined by the 3σ contour as shown in Fig. 1. The 1σ uncertainty is 0.72, 0.72, and 1.39 mJy, respectively. The grey dashed line denotes the marginal detection at ∼46 km s−1.
