Top panel: radio contours at 1.5 GHz for the cluster MACS J0417.5−1154 overlaid on the Chandra X-ray image. Discrete sources have not been subtracted. The HPBW is 26.7″ × 18.8″ (PA = −1.2°). Contours are placed at 0.05, 0.1, 0.2, 0.4, 0.7, 0.9, 3, 5, 7, 9 mJy per beam; the noise level is 0.02 mJy per beam Bottom panel: contours of the diffuse radio source classified as a radio halo at the cluster center superposed on the optical image. Discrete sources in the halo region have been subtracted. The HPBW is 15″. The noise level is 0.03 mJy per beam; the shown contours mark −0.07, 0.05, 0.07, 0.1, 0.15, 0.3, 0.5 mJy per beam.
