Left and Middle: contour maps of H₂O (yellow), [O I] (red, left), and CO (red, middle) emission compared with continuum emission (color contours) at 63.3 μm (left) and 108.5 μm (middle). The insets show the spatial extent of continuum and line emission in the different components along the N-S outflow axis. Right: a comparison of the location of emission in H₂O 63.32 μm (blue), 108.5 μm continuum (red), Spitzer-IRAC 4.5 μm photometry (color contours; Jørgensen et al. 2006; Gutermuth et al. 2008). All contours have levels of 0.1,0.2,0.4,0.8, and 1.6 times the peak flux near IRAS 4B. The asterisks show the sub-mm positions of IRAS 4B near the center of the field and IRAS 4A in the NW corner. Some noise in these maps is suppressed at empty locations far from IRAS 4A and IRAS 4B.
