Average cumulative number of SHs (top panel) and the same value normalised to unity (bottom panel) within a given projected cluster-centric distance in units of the host virial radius. Here, we only consider the four Dianoga regions in common between all four setups in Table 2, and SHs within a projected distance of R <  0.15R_vir and a total mass greater than 2 × 10¹⁰ h⁻¹ M_⊙. The black, cyan, and pink lines refer to the 10×, 1 × R15, and 1 × RF18 simulations, respectively. Shaded area shows data from Bergamini et al. (2019).
