Stellar mass fraction for the BCG, ICL and rest of stars. The bar shows the median value for the 324 clusters, while the error bars indicate 16th–84th percentiles. The fraction is computed dividing the stellar mass content in each of the components by the total stellar mass inside R₅₀₀, M_*, 500. The straight and dashed bars separate into relaxed and disturbed clusters based on their χ_DS value at R₅₀₀. “Relaxed” clusters are the 50 clusters with the highest χ_DS, while “disturbed” are the 50 clusters with the lowest value of χ_DS. As before, green bars are for GADGET-X, while magenta ones are for GIZMO-SIMBA results.
