Clumps’ number density for the same cluster at different levels of numerical resolution in function of radial distance from the cluster’s center. The dot-dashed lines represent the median value computed between R_500, c and 2.5 ⋅ R_500, c, while the dashed ones represent the median value computed from 2.5 ⋅ R_500, c to 5 ⋅ R_500, c. The color-coding of these lines is the same adopted for the dots.
