Fig. 3

Top left: feathered 160 μm image of HiGal–11, shown on a log scale to highlight low emission regions at large scales where our method has the most impact. Top right: ratio of the feathered image over the constant-offset image. Bottom row: from left to right, same as in the top right panel for 250 μm, 350 μm, and 500 μm, showing the same colorbar in every case.
