Re-calibrated Herschel/PACS images at 70, 100, and 160 μm (from left to right). The scaling in the three panels is from −3.8 to 4.0, from 5.0 to 17.6, and from 33 to 45 mJy pixel^-1, respectively. The 3.2 mm continuum contours are from 3σ and continue in 2σ steps with a 1σ value of 0.08 mJy beam^-1. A scale bar and the 3.2 mm synthesized beam are shown in each panel, and the three main sources are labeled in the bottom left panel. The 70, 100, and 160 μm PSFs are 5.6′′, 6.8′′, and 11.3′′, respectively.
