CO (6–5) outflow emission in the OMC-3 MMS 1–6 region. Blue contours are for the blue-shifted emission in the range from −25 to +7 km s⁻¹; while red contours are for the red-shifted emission from +16 to +31 km s⁻¹. The first contour is 3σ and contour spacing is 2σ (σ = 1.9 and 0.8 K km s⁻¹, for blue- and red-shifted emission, respectively). The black solid and dashed contours are the blue- and red-shifted CO (3–2) emission, respectively, as presented by T08. The black square shows the whole field covered by our CHAMP+ observations. The triangles show the positions of the continuum sources and the green dashed lines indicate the outflow orientation (both according to T08).
