Orbit anisotropy of dark matter haloes with Schwarzschild modelling

We apply the Schwarzschild orbit superposition method to mock data in order to investigate the accuracy of recovering the profile of the orbit anisotropy. The mock data come from four numerical realizations of dark matter haloes with well defined anisotropy profiles. We show that when assuming a correct mass distribution we are able to determine the anisotropy with high precision and clearly distinguish between the models.
