Evidence for a molecular outflow towards the core. We show in contours the CO (2–1) emission integrated in the ranges 40–70 km s⁻¹ (blue contours) and 85–115 km s⁻¹ (red contours). The background grey-scale image shown in both panels is the 1 mm continuum emission (see Fig. 1). Highlighted is the associated blueshifted outflow lobe (no redshifted lobe is obvious due to line-of-sight contamination at higher velocities). Shown in the bottom right is the beam size of the observations. Figure B.1 shows channel maps of the CO emission across the region.
