Top-left: 3D dark matter density profile for the PlumCoreOM mock galaxy, bands denote the 95% CL regions from the median for different numbers of stellar tracers including both LOS and PM velocities. The results from Read et al. (2021) for AGAMA f(E, L) models, and from Collins et al. (2021) for GRAVSPHERE1.5 (including LOS VSPs) for 1000 tracers with their respective median values with 95% CL errors are shown for comparison. The red line denotes the true analytical solution from which the mock was generated. The gray, dashed line corresponds to the projected half-light radius (R_1/2). Top-right: same as the left hand side but for the PlumCuspOM model. Bottom-left: symmetrized anisotropy profile for the PlumCoreOM model. The red line again denotes the true solution from which the mock was generated, corresponding to an Osipkov-Merritt profile. Lower right: same as the left hand side but for the PlumCuspOM model.
