Cutouts (60″ × 60″) showing prototypical compact (left) and complex (right) radio morphologies with light red contours marking several factors of the local noise (at rms × [2, 4, 6, 12, 24, 48]) and magenta circles indicating the radio centres. The beam size is depicted as a hatch-filled circle in the bottom left corner. In grey scale, the LS9 r-band image depicts the host galaxy, with its optical centre marked with a green cross. Radio intensity maps, with a colour bar indicating the peak flux, are also shown for these two examples.
