XMM-Newton 0.3–7 keV image of A370 overlaid with the radio contours with compact sources subtracted from the uv-data (325 MHz, top left; 1.5 GHz, top right). All the point source in XMM-Newton image are removed and smoothed with a Gaussian with scale of 3 pixels across. The Blue dashed curves show the surface brightness edges found by Botteon et al. (2018). Bottom left: Chandra 0.5–2.0 keV image overlaid with the 3.0 GHz radio contours with compact sources subtracted from the uv-data. The radio beam size is 25.0″ × 22.0″. Contour levels are drawn at [1, 2, 4, 8,...] × 3σ_rms, where σ_325 MHz = 161 μJy beam⁻¹, σ_1.5 GHz = 34 μJy beam⁻¹, σ_3.0 GHz = 18 μJy beam⁻¹. The inner uv-cut of 0.22 kλ is adopted for 325 MHz and 1.5 GHz images. Bottom right: GMRT 325 MHz image of A370 depicting the region (magenta ellipse) where we extract the integrated flux densities.
