Channel map of the CH₃CN (J = 12–11) K = 3 line ranging from 17.9 to 26.3 km s⁻¹ in steps of 0.3 km s⁻¹. The contours of the CH₃CN emission are at the 3, 5 and 10 σ level (σ = 2.0 mJy beam⁻¹ chan⁻¹). In the central panel at the V_LSR velocity channel (22.1 km s⁻¹) the dotted line indicates the PA of the disc major axis at 30°, while the solid (blue and red) line indicates the outflow direction at a PA of 135°. At all velocities the CH₃CN emission is brightest to the south west of the main continuum peak (at 0,0 indicated by the “+” symbol). The plume structure (indicated) is visible between ~19.7 and ~22.5 km s⁻¹ while the knot at the tip of the plume is inward of the diffuse dust emission, potentially indicative of an interaction of outflowing material with the surrouding dust structures. The continuum emission at the 3, 4, 5 σ levels as in Fig. 2 is plotted in black contours in the 20.7 km s⁻¹ channel panel to highlight the diffuse dust emission. A scale bar and synthesised beam are shown in the bottom left panel.
