XMM-Newton [0.3−2] keV energy band images of confirmed cluster candidates. North is up and East is to the left. Image sizes are 3θ₅₀₀ on a side, where θ₅₀₀ is estimated from the M₅₀₀ − Y_X relation of Arnaud et al. (2010) assuming standard evolution. Images are corrected for surface brightness dimming with z, divided by the emissivity in the energy band, taking into account galactic absorption and instrument response, and scaled according to the self-similar model. The colour table is the same for all clusters, so that the images would be identical if clusters obeyed strict self-similarity. A yellow cross indicates the Planck position and a red/green plus sign the position of a RASS-BSC/FSC source. The clusters are sorted according their estimated redshift. For the double systems (last two rows) the middle and right panels show the two components and the left panel the wavelet-filtered overall image.
