Variation of the TATT parameters for the halo sample of the 2.8 Gpc box with halo mass M_h (in our case, we use M_200mean as the mass of the halo). The different lines correspond to the four types of inertia tensors. A₁ is a power law of M_h irrespective of inertia tensor choice. Similarly, the functional forms for the variation of A₂/A₁ and A_1δ with mass for the TATT-M model hold for all choices of inertia tensors considered. We omit the error bars on the fits for clarity.
