Same as Figs. A.1-A.4, but for the two-population models (Sect. 5). From top to bottom and left to right, the panels show the mean metallicity $Z_0^1$, metallicity dispersion ${\sigma }_Z^1$, anisotropy ${\beta }_z^1$, rotation parameter κ¹ for the high [M/H] population, $Z_0^2,{\sigma }_Z^2,{\beta }_z^2,{\kappa }^2$ for the low [M/H] population, inner population fraction h₀, outer population fraction h_∞, the transition radius log(R_h), fraction of background stars ϵ in percent, and the mass-to-light ratio 𝚼. The black hole mass is fixed to 4.3×10⁶ M_⊙, dark matter is not considered in the gravitational potential.
