Distribution of the blue (greyscale) and red lobes (contours) of outflowing gas as detected in some of the transitions. The ‘+’ marks the position of the massive YSO. Contour levels are in K km s⁻¹. For CO(2–1) blue contours are at 10–45 in steps of 5 and red contours are at 15 to 85 in steps of 5. For H₂CO(3–2) blue contours are at 0.3 to 1.0 in steps of 0.1 and red contours are at 0.3–0.7 in steps of 0.1. For SO(5₆–5₄) blue contours are at 0.3–0.1 in steps of 0.1 and red contours are at 0.3–1.4 in steps of 0.1. In all panels the velocity ranges used for integration for the blue and red lobes are marked.
