Scaled density profiles of the new Planck SZ clusters compared to those of similar mass systems from the representative X-ray samples REXCESS (Böhringer et al. 2007) and EXCPRES (Arnaud et al., in prep.). R₅₀₀ is estimated from the M₅₀₀–Y_X relation of Arnaud et al. (2010). Thick lines show the mean profile of each sample. The density profiles of the Planck SZ-selected clusters are on average shallower than those of the X-ray selected clusters of the same mass.
