Best-fit values of r_s, c, gas mass fraction f_gas at R₅₀₀ and dark mass M_DM within R₂₀₀ as obtained from Method 1 (diamonds; the ones including red points indicate the objects where the condition (r_s + ϵ_rs) < R_sp is satisfied by both methods. R_sp here plotted as horizontal line in the upper panel).
