Results for the mass - anisotropy profiles and mass model / pulsar distribution parameters. Upper left: 3D enclosed mass profile including photometric, central remnants, black hole, and MSP mass components. The solid lines correspond to the maximum posterior with 68 and 95% CL regions. The black and gray dashed lines indicate the upper limit of the 95% CL region for the black hole and MSP components, respectively. Upper right: symmetrized anisotropy profile including the maximum posterior and 68 and 95% CL regions. The posterior distributions for the anisotropy parameters are presented in Appendix A. The profile is close to isotropic, with a mild radial (tangential) anisotropy in the inner (outer) regions. This translates to the 1σ CL band being well within | β˜|$\left| {\tilde \beta } \right|$, or |β| ≲ 0.15 for the vast majority of the range covered. Lower left: posterior distributions for the masses of the various fitted components of our analysis, indicating the median and 68% CL region at the top of each distribution. Lower right: posterior distributions for the morphological parameters of the fitted mass profiles with respective median and 68% CL regions.
