Dynamical models of NGC 7507. Black circles indicate in all panels the line-of-sight velocity dispersion. All models are given outside of 400 pc, where the luminosity model is unaffected by seeing. Top left: stars-only models. The black solid line is an isotropic model using M/L_R = 3.13. This model is shown in all panels as a comparison. The red dotted line is the best-fit model for a constant anisotropy using β = 0.12, while the blue dashed line is a fully radial model (β = 1). The green dashed line is the model using the anisotropy as given in Eq. (16), while the green dot-dashed line is a model using the Osipkov-Merrit anisiotropy (Eq. (17)). The red solid line is a model with M/L_R = 2, based on Tortora et al.’s stellar population analysis (see Sect. 5.1). Top right: MOND predictions using the “simple” and “standard” interpolation formulae. The dashed red area is an isotropic model, while the blue area indicates a fully radial model for the former interpolation. Bottom left: NFW models using c = 5 and c = 10. Parameters for each model are reported in Table 6. Bottom right: Logarithmic dark halo models. Using β = 0,  β = 0.3, and MŁ anisotropy. Parameters for each model are given in Table 7.
