Dependence of the velocity segregation on luminosity in bins of the magnitude gap for galaxies within R₂₀₀. We show with black filled squares those clusters with Δm₁₂ ≤ 0.5, with red filled hourglasses those with 0.5 <  Δm₁₂ ≤ 1.0, with violet filled bow ties those with 1.0 <  Δm₁₂ ≤ 1.5, and with green filled circles those systems with Δm₁₂ ≥ 1.5. The error bars show the uncertainties of the mean, computed as the standard deviation of the normalised velocity divided by the square root of the total number of galaxies in each absolute-magnitude bin.
