Results from parametric 2D modeling with PYAUTOGALAXY. Each row shows a different source and/or image. Left column displays the observed emission, while the right column shows the residuals after subtracting the maximum likelihood model. The first and second rows show the modeling of the DSFG’s [C II] emission and 160 μm dust continuum, respectively. Black contours represent the ±3, 9, 27 and 81σ levels. Results for the [C II] emission of CRISTAL-01a (CRISTAL-1) are shown in the third row. Here, the contours only trace ±3, 4 and 5σ levels.
