Velocity anisotropy profiles of the red and blue cluster members in the upper and lower panels, respectively. The solid (dashed) coloured lines represent the solutions of the inversion of the Jeans equation adopting the mass profile from Sartoris et al. (2020) (Umetsu et al. 2016). The coloured area indicates the 68% confidence region around the solution. The magenta shading indicates the 68% confidence region around the MAMPOSSt best-fit solution for a Tiret model (Sartoris et al. 2020). In both panels we use the same Tiret model, which was computed considering the full sample of member galaxies. The vertical dotted and dash-dotted black lines mark r₋₂ (which corresponds to r_s for an NFW model) and r₂₀₀ obtained from Umetsu et al. (2016) and the MAMPOSSt analysis of Sartoris et al. (2020), respectively.
