Spitzer RGB image with overlaid LABOCA 870  μm contours, shown for the same field as in Smith et al. (2010a) for identifying Herbig-Haro jets. The first three contour levels are 0.06, 0.12, and 0.18 Jy/beam, while the further levels increase by a factor of the square root of two. The jet sources in the region are marked in green. Circles indicate sources of HH jets and candidates, diamonds those of EGOs, and squares compact green objects. The sources of MHOs are marked by crosses.
