Left: SRT radio image at 6600 MHz (contours) overlaid on the ROSAT PSPC X-ray image (colors) in the 0.4–2 keV band. The SRT image results from the spectral average of the bandwidth between 6000 and 7200 MHz. It has a sensitivity of 1 mJy/beam and an angular resolution of 2.9′. The first radio contour is drawn at 3 mJy/beam (3σ_I) and the rest are spaced by a factor of . SRT sources with an NVSS counterpart are labeled with the letters A to S. The X-ray image (ID = 800316p) is exposure corrected (T_exp ≃ 24 ks) and adaptively smoothed (see Sect. 4.3). The green circle is centered on the cluster X-ray centroid and the radius indicates the cluster core radius r_c. Right: VLA radio image at 1443 MHz (contours) is overlaid on the optical emission in the g^Mega band (grayscale). The VLA image has a sensitivity of 0.34 mJy/beam and an angular resolution of 19′′. The first radio contour is drawn at 1 mJy/beam (3σ_I) and the rest are spaced by a factor of 2.
