Fig. 7.

Top panel: radio image of MACS J0454.1−0300 at 1.5 GHz superposed on the optical image. Discrete sources are labeled as A, B. The image has a FWHM of 33″ (circular). The contour levels are (3, 6, 9, 12, 24, 48) × σ with σ = 0.043 mJy per beam. Bottom panel: radio contours of the halo at the center of MACS J0454.1−0300 overlaid on the X-ray image obtained by Chandra (colour). The HPBW of the radio data is 40″ and the noise level is 0.04 mJy per beam. The shown contours mark 0.1, 0.4, 1.2, 4.8, 9.6 mJy per beam.
