First-moment maps and contours of the total intensity of CO 3–2 (left panel) and SiO 8–7 (right panel) in V1309 Sco. The first-moment maps provide a view on the intensity-weighted mean velocity in the given pixel. The contours are drawn at 5, 10, 20, 40, 60, and 80% of the respective emission peaks. Beam sizes are marked in the corners. The dashed line is drawn at a PA = 151° along which the emission is slightly more extended.
