Channel maps of SO 9₈−8₇ (top) and SO₂8_2,6−7_1,7 (bottom) at systemic, low (LV), intermediate (IV), and high (HV) velocities (panels from left to right). The green, blue, and red contours trace the emission at systemic velocity and over the labelled blue- and red-shifted velocity intervals (| V − V_sys |). The lowest contour of the emission at systemic velocity is shown in all panels. The first contour is at 5σ for SO and 3σ for SO₂ with steps of 5σ (V_sys) and 20σ (LV, IV, HV) for SO and 3σ for SO₂ (1σ ~ 3−4 mJy/beam/0.43 km s^-1). The tilted black cross is centred at the source position and indicates the jet and the disk PA (PA_jet = 22°, PA_disk = 112°). The ellipse in the bottom-left corner shows the beam HPBW of the line emission maps (, PA = 49°). The triangles indicate the emission peaks along the blue and red lobes.
