From left to right: position-velocity (PV) diagram of CO 3−2, SiO 8−7, SO 9₈−8₇, and SO₂8_2,6−7_1,7 lines obtained along the jet (PA_jet = 22°, top) and the disk (PA_disk = 112°, bottom). Horizontal and vertical dashed lines mark V_sys = + 1.3 km s^-1 and the continuum peak MM1. The red arrows on the SO₂8_2,6−7_1,7 PV indicate emission from complex organic molecules, which is blended with the SO₂ emission at the source position. For CO 3−2, SiO 8−7, SO 9₈−8₇, SO₂8_2,6−7_1,7 the first contour is at 5σ (σ = 10 mJy for SiO, 4 mJy for SO, and 3 mJy for SO₂) with steps of 10σ (CO, SiO, and SO), and 5σ (SO₂).
