Scaling of the percentage of resolved SubFind galaxies in the 12 clusters analyzed at z = 0 (CL-[2-13]), identified by our stellar SubDLe, with cluster properties: total virial mass (upper panel), mean inter-galaxy separation within one virial radius (middle panel), and median galaxy stellar mass (lower panel), color-coded with the total number of SubFind galaxies (the ones we consider resolved enough, with at least 100 star particles). The circles represent clusters that required a treatment with sparsely distributed sub-grids (with M_th = 0) and the diamonds represent the three smaller clusters that did not require it.
