(Analytical) initial (i.e., ΔM_• [ M₉ ] = 0, black dashed line) and final velocity distribution, , of our most extreme Models 8 and 9. We use the 3D radius for the evaluation of the velocity dispersion components, σ_θ,σ_φ,σ_r. Error values are obtained from the bootstrapping method. Particles on eccentric orbits are attracted more strongly toward the innermost center such that circular orbits, i.e., a tangential biased region develops slightly outside but still very close to the center. This effect is relevant for the stellar dynamical mass measurement of the central black hole.
