Top panel: cumulative distribution of luminosity of simulated clumps (in black; the average over the whole data set is considered) and of point-like sources in the ROSAT observation of A2142 (in orange, taken from Eckert et al. 2012). The solid lines show the distributions inside 0.1 ≤ R/R₂₀₀ < 0.6; the dot–dashed lines show the distribution inside 0.6 ≤ R/R₂₀₀ < 1.2. Bottom panel: cumulative radial distribution of simulated clumps and point-like sources for the same data sets.
