SiO (J = 7–6) compact bipolar outflow emerging from clump S. Top: velocity-channel maps rotated clockwise by PA = 21°; contours are 1σ, 2σ, 3σ, 5σ, 7σ, 10σ... by 5σ (σ = 10 mJy/beam). The rms of the line-free dv = 1 km s⁻¹-channel maps is 2.7 mJy/beam. The background image is the 330 GHz-continuum map. Bottom-left: order-zero moment map over the V_LSR = [18–53] km s⁻¹ velocity range; contours as in top panel but with σ = 90 mJy/beam km s⁻¹. Bottom-right: axial position-velocity diagrams along PA = 21°; contours are 1σ to 6σ by 1σ, and from 8σ... by 2σ (σ = 9 mJy/beam). The lines represent different velocity gradients implying different kinematic ages at various regions of the SiO-outflow (dashed-black: the SiO-knots, dotted-black: flame-shaped lobes – average).
