Channel maps of the ¹²CO J = 3–2 emission with the low-offset velocities. Contour levels are at 6, 10, 18, 40, and 50σ (σ = 0.022 Jy beam⁻¹) and channel separation is 2 km s⁻¹. The synthesised beam is plotted in the lower left corner of the −28 km s⁻¹ channel. The local standard-of-rest velocity is given in the upper right corner of each channel. A cross denotes the stellar position determined from the continuum emission. Colour code for the flux density (Jy beam⁻¹) is given in the colour bar.
