Maximum radius to which the ICL can be detected, R_max, interpolated across halo mass,  log₁₀ (M_h/M_⊙), and redshift, z, for a fixed f_ICL = 0.15 in the left panel and across ICL fraction, f_ICL, and redshift, z, for a fixed halo mass,  log₁₀ (M_h/M_⊙) = 14.7, in the right panel. Coloured circles indicate the measured R_max values from individual mock clusters. Contours show the limiting radial extent expressed in physical units by the solid lines and in terms of R₂₀₀ by the dashed lines, where the value of R₂₀₀ corresponds to a typical cluster at the corresponding location in the parameter space.
