Chandra image of AS1063 overlaid with the radio contours of diffuse emission in AS1063 at three frequencies (325 MHz, top left; 1.5 GHz, top right; 3.0 GHz, bottom left). Chandra images are all in the energy band 0.5–2.0 keV with pixel size 4 × 0.492″ and smoothed with a Gaussian with scale of 3 pixels across. Contour levels are drawn at [1, 2, 4, 8,...] × 3σ_rms, where σ_325 MHz = 96 μJy beam⁻¹, σ_1.5 GHz = 40 μJy beam⁻¹, σ_3.0 GHz = 24 μJy beam⁻¹. Compact radio sources were subtracted in all radio images. The inner uv-cut of 0.15 kλ is adopted for all radio images. Bottom right: VLA L-band image of AS1063 depicting the region where we extract the integrated flux densities. The cyan polygon indicates the region where the diffuse AGN component is subtracted from the total flux measurement (magenta polygon).
