Radio surface brightness profiles of MRC 2011-298. Top: Sampling regions overlaid on the radio contours at 700 (left) and 9000 (right) MHz. The identifier of the sampling regions increases towards north and west, and decreases towards south and east with respect to region ‘0’ (in red), which includes the radio core. Bottom left: Profiles of the active lobes and wings measured at 700 (blue) and 6063 (red) MHz in boxes of beam-size (7″) width, and normalised by the brightness of region ‘0’ (dashed black line). Bottom right: Profiles of the jets measured at 2988 (orange), 6063 (red), and 9000 (blue) MHz in beam-size (4.5″) circles, normalised by the brightness of region ‘0’ (dashed black line).
