Brightness temperature ratio (T₃₂/T₂₁) and CO(2-1) velocity dispersion maps. The left panel shows the T₃₂/T₂₁ map at 06 resolution with the VLA 6 GHz HR contours overlaid in black (at 4, 8, 16, 32, and 64σ_rms, with σ_rms = 23 μJy beam⁻¹). The PA_jet = 60° is indicated as a black solid line. The orientation and width (06) of the slits used to produce the PVDs shown in Fig. 2 are indicated as grey shaded areas. The middle panel corresponds to the σ map of the CO(2-1) line emission at 02 resolution. The cyan star in the left and middle panels indicates the peak of the 220 GHz ALMA continuum. On the right panel, we show the σ map of the gas from Simulation E in Meenakshi et al. (2022) for a jet power of P_jet = 10⁴⁵ erg s⁻¹, inclined 20° from the CO disc plane, and with an angle of ∼25° relative to the LOS.
