Dust continuum flux density maps of the Hot DOG sample. The beam is shown as a white ellipse on the bottom-left, together with its size and the depth (rms) of the collapsed, line-subtracted cube. The dashed white circumference denotes the aperture used to extract the spectra shown in Fig. 2. The dotted contour shows the zero-flux intensity, and the solid contours represent the [2.5, 3.0, 2^{(4 + n)/2}]-σ levels, where σ is the rms of the map and n = [0, 1, 2…]. Symmetric, negative levels are shown as dashed contours. Field of views (FoVs) of 2″ and 4″ on a side are displayed depending on the galaxy. Roughly, 1″ ≃ 7 kpc.
