Fig. 8.
Left panel: low-resolution, 30″ × 30″ VLA 1.4 GHz image contours overlaid on the Chandra image. The VLA contours (white) show the (1, 2, 4, …)×3 × σVLA, where σVLA = 55 μJy beam−1. Region B was used to extrapolate the radio halo flux (see Sect. 3.3). Right panel: same low-resolution VLA image contours (in black) overlaid on the LOFAR 150 MHz extended emission subtracted image. Region A shows the portion where the radio halo emission is not contaminated by the RP and HT.
