Results of the regular grid search for Schwarzschild models with different stellar mass models.

Notes. This table summarises the results of Sect. 4.3. Column 1: details of the stellar mass model used for the dynamical modelling. Columns 2 and 3: parameters of the best-fitting models derived from the regular grid search: black hole mass MBH and scaling factor S. Column 4: χ2 over the degrees of freedom. The uncertainties were calculated using 3σ confidence intervals. *For the model with constant mass-to-light ratio, the mass scaling factor S corresponds to the derived stellar M*/LF850 in M⊙/L⊙.
