Top: total intensity radio contours at 1400 MHz with the VLA in D configuration after subtraction of discrete sources. The image has a FWHM of 42′′  ×  45′′ (PA = 10.3°). The contour levels are drawn at  −0.3 (thin-dashed lines), 0.3 mJy beam^-1, and the rest are spaced by a factor of 2. The sensitivity (1-σ) is 0.1 mJy beam^-1. Crosses indicate the positions of the subtracted discrete sources. Arrows indicate hints of possible diffuse emission left after the subtraction process. Bottom (left): zoom of the “Main” cluster in which the total intensity radio contours are overlaid on the red plate of the Sloan Digital Sky Survey. Bottom (right): zoom of the “Main” cluster in which the total intensity radio contours are overlaid on the XMM X-ray image.
