Top panel: MACS J0257.6−2209 (A402) – radio contours at 1.5 GHz (total intensity) as detected with the JVLA in C+D configuration overlaid on the Chandra X-ray image (color). The radio HPBW is 37″ (circular). Contour levels are 3, 6, 9, 12, … × σ with σ = 0.048 mJy per beam. Bottom panel: C array image of compact sources in the field of MACS J0257.6−2209, obtained with the longest baselines only, overlaid on the optical image. The HPBW is 15″ (circular). Contour levels are 3, 4, 6, 9, 24, 38, 48, 78, 96 ×σ with σ = 0.04 mJy per beam. Discrete sources are labelled as A, B, C, D, and E.
