Trajectories of the wind in the z − R plane (y and x axis, respectively) for λ_Edd = 0.1, 1.0 (left and right panel, respectively). Solid (dashed) lines correspond to v_z,0 = v_rot(10⁻² v_rot). Thick and thin lines refer to the relativistic and classic (i.e. non-relativistic) treatment. Distances are reported both in units of r_G and pc, where the latter are calculated assuming M = 10⁸ M_⊙.
