Projected phase space and velocities histogram distribution for all of the 11 867 galaxy members in our sample. Member velocities are normalised to the mean cluster velocity dispersion, whereas the distance to the centre of the cluster is normalised to the value of r₂₀₀ in each cluster. Horizontal black dashed lines are the 2.7σ clip. The red line represents a Gaussian (normal) fit to the velocity histogram with σ = 1.
