Left panel: scaled total density profiles computed using the mass profiled derived from the DF Einasto model. For each cluster, the total radial range is that of the combined density profile; estimates beyond the radial range covered by temperature measurements are marked with dotted lines. The grey lines represent the scaled total density profiles derived from the REXCESS sample. Right panel: scaled mass profiles. The colour scheme is the same as in the left panel. The black error bars in both panels represent the 68% dispersion of the REXCESS profiles at 0.1 and 0.5 .
