Top panel: time to accrete half of the total mass of the torus as a function of q (plasma parameter β = 3). In agreement with the graph of M_d(t) in Fig. 5 we notice a higher rate of accretion (shorter accretion half-time) for lower values of q. Bottom panel: the dependence of accretion half-time on the plasma magnetization parameter β is shown; the power-law index of the angular moment radial profile is set to a fixed value q = 1.1.
