Comparison of SMA continuum emission (grayscale) with: a) 850 μm JCMT emission, where the JCMT contours range from 0.5 to 20 Jy beam^-1 in steps of 1 Jy beam^-1 (Johnstone & Bally 1999); and b) VLA NH₃ (1,1) emission integrated from 4.6 to 12.3 km s^-1, where two lowest NH₃ contours are 20 and 100 mJy beam^-1 km s^-1 and the higher level contours continue in steps of 100 mJy beam^-1 km s^-1 (Wiseman & Ho 1998). Coordinate offsets are measured with respect to (α,δ) = (05^h35^m17.0^s, −05°22′00.0′′) (J2000.0).
