Different spherical Jeans models fitted to our combined surface brightness profile for fixed anisotropy β = 0.1. The upper panel shows the models together with the data for different black-hole masses, the thick black line indicates the best fit. The lower panel shows the χ² values as a function of black-hole mass, and the dashed line denotes Δχ² = 1. The best fit with χ² = 1.89 requires a black-hole mass of M_• = () × 10³ M_⊙.
