Top panel: time evolution of the averaged velocity, v_PI, of three parasitic modes from the run b0m-dh: the fastest (red), another that saturates at later times (yellow), and one mode that does not saturate (blue). Middle panel: time evolution of the parasitic wavevector k_h. Bottom panel: time evolution of the angle θ between the wavevector k_h and the radial direction, $\check{\mathbf{x}}$. The modes start growing faster when k_h and θ approach the values found in Pessah (2010), denoted as $k_{\mathrm{h}}^{\mathrm{P}10}$ and θ^P10, respectively.
