Dynamical models. Black open diamonds are the measurements from S12, while blue triangles are the velocity dispersions from the current work. Left panel: models which consider all the velocity dispersion points. The solid black curve is the stars-only model. The red dotted curve is the best-fitting model with β = 0.3 and NFW halo with c = 10. The green dashed curve is the model under the anisotropy by Mamon & Łokas (2005) allowing the maximum amount of dark mater. Right panel: same as in left panel, but excluding the velocity dispersion between 70′′<R< 80′′ when performing the fits.
