XMM-Newton smoothed images in the [0.3–2] keV band of the ATCA cluster sample overlaid with the contours of the high resolution wide band radio maps (see Table 3 and Figs. A.1 and A.2) in red and the same contour levels for the Block 3 low resolution compact source subtracted maps for the two clusters with diffuse radio emission (see Sect. 6) in blue. The background of the X-ray images has been subtracted. The X-ray images are corrected from surface brightness dimming with redshift, divided by emissivity in the energy band, taking in account absorption from the Galaxy and the response of the instrument. Finally the images are scaled to a self-similar model. The colours are selected so that the images would look identical when scaled by their mass if they were at the same distance; this gives us a visual hint of the dynamical state of the clusters.
