Results of the gOM anisotropy model for the major cluster member populations. In the left column, we show the β(r) values, while, on the right one, we plot those of β′(r) = σ_r/σ_ϑ. The four rows are organised to distinguish the different mass and number density models adopted in each situation, and they are specified on the label of each vertical axis. The shadowed region represents the 1σ confidence interval, while the yellow line represents the R_200c of the stacked cluster.
