Velocity-integrated intensity maps of the ¹²CO(2–1) line (upper row) and the vibrational ground-state line of SiO(6–5) (lower row), covering three velocity intervals. Left: blue line wing [v_lsr,* − 10,v_lsr,* − 2] km s⁻¹, middle: line center [v_lsr,* − 2,v_lsr,* + 2] km s⁻¹, right: red line wing [v_lsr,* + 2,v_lsr,* + 10] km s⁻¹. North is up and east is to the left. We note the different color scales. Contours are plotted every 5σ for CO and every 20σ for SiO, where (from left to right) 1σ = 14.6, 22.0, 19.2 mJy beam⁻¹ km s⁻¹ for CO(2–1) and 1σ = 11.1, 16.7, 16.4 mJy beam⁻¹ km s⁻¹ for SiO(6–5). The black ellipse in the lower left corner indicates the synthesized beam.
