SABOCA 350 μm image of NGC 3603 MM2. The source labeled “9” (S9 ) is associated with IRS 9A. This source and the source labeled “c” (Sc ) were the targets of SHFI spectroscopy. The source labeled “g” (Sg ) is at the tip of the eastern pillar (see Figs. 1 of Brandl et al. 1999; and Mücke et al. 2002), while the source labeled “8” (S8 ) is at the tip of the western pillar, both pointing toward the OB cluster. The wedge at the bottom shows the scale for the image flux densities in Jy/Beam.
