Results of the triaxial Schwarzschild modelling performed with DYNAMITE. After constraining the intrinsic shape and dark matter parameters, a fine grid of models was run to derive the mass scaling factor S and the central black hole mass M_BH. S accounts for differences in the stellar M/L derived from SSP modelling and dynamical modelling. Each Schwarzschild model is indicated as a grey dot. The overplotted contours indicate the levels. We show the results from all three modelling runs with different assumptions on the stellar mass-to-light ratio M_*/L in this figure. The coloured contours indicate the 3σ confidence intervals for the different modelling runs. The mass measurements are robust as indicated by the closed χ²-contours outside of the 3σ confidence interval. The best-fitting models were derived as the minimum of the χ² distribution and are indicated with a red dot, respectively. For the models with constant stellar M/L, we normalised the dynamical stellar M/L by the best-fit M/L. The vertical black line indicates the smallest black hole mass that we expect to robustly detect based on the SoI argument and the spatial resolution of the SINFONI observations.
