SMA 1.3 mm continuum (contours at 3σ, 6σ, 9σ, and then increasing in steps of 10σ, where σ = 4.7 mJy beam^-1) and SCUBA 850 μm continuum (colour scale). The two circles show the primary beams of the two SMA pointings. The box shows the coverage of the APEX short-spacing data. The synthetic beam size of the SMA observations is 6.0″ × 2.9′′. Refer to Fig. 1 for a guide to the symbols used for the compact objects.
