Velocity anisotropy (Eq. (19)) profiles of E, S0, and S galaxies from MAMPOSSt for model 24 (NFW with T-TAND anisotropy for spirals only, upper left), model 9 (NFW with T-TAND anisotropy, upper right), model 1 (gNFW with T-TAND anisotropy, lower left), and model 7 (gNFW with T anisotropy and free anisotropy radius, lower right) for sigv-stacked pseudo-cluster. The hashed regions indicate the 68% confidence zone, while the curves display the 5th and 95th percentiles. The thick vertical gray line indicates the position of r₁₀₀ = 1.35 r₂₀₀, which is close to the theoretical virial radius, where its width shows the uncertainty on log r₂₀₀.
