Continuum emission from FIFI-LS at wavelengths above 100 μm. The maps show (from top to bottom) the distribution of continuum emission with contours in the vicinity of the [O I] line at 145.53 μm (10, 15, 20σ), the [C II] line at 157.74 μm (6, 12, 18σ), and the CO 16–15 and 14–13 lines at 162.81 (10, 20, and 30σ) and 185.99 μm (5, 10, and 15σ). The beam size is shown for the CO 14–13 line at 185.99 μm.
