Average density and mass radial profiles as a function of redshift. Upper panel: Ratio between the median shell density of clusters at the six redshifts z = 0.01, 0.21, 0.42, 0.62, 0.82, and 1.04 relative to z = 0.01. The color coding is shown in the legend. The thick section of each ratio shows the infalling shell (Sect. 4.1, Table 3). Bottom panel: Same as the upper panel but for the median cumulative mass profile.
