Average rescaled matter profile $\stackrel{\sim }{\mathrm{\Delta }\mathrm{\Sigma }}(R/R_{200\mathrm{c}})$ of the full sample of 698 clusters over the full mass and redshift ranges estimated using the mean mass posterior $P(M_{200\mathrm{c}}|\widehat{\zeta },\widehat{\lambda },z,\mathit{p})$ for each cluster (see Eq. (49)). The black points represent the measured mean profile, and the error bars include not only shape noise but also marginalization over the cluster mass uncertainties. The dark and light-shaded red bands show 68% and 95% credible intervals, respectively, on the model profile extracted from hydrodynamical simulations.
