Different contributions to the emission at 1.2 mm. a) Total emission observed with SIMBA. b) Free-free emission at 1.2 mm estimated from the ATCA image at 8.6 GHz, as showed in Eq. 5. c) CO(2–1) contribution to the 1.2 mm emission as observed through the SIMBA bolometer array (see Eq. (6)). The red contour corresponds to the CO(2–1) emission at 0.5 mJy beam^-1. d) N11 dust emission at 1.2 mm obtained after subtraction of the free-free and CO contributions to the total 1.2 mm emission. All the images are in units of mJy beam^-1. Intensities of the images b) and c) were amplified by a factor 6. In all the images, the black contours correspond to 3σ (12 mJy beam^-1) of the total 1.2 mm emission.
