Mean perpendicular coordinate in isotropic magnetostatic turbulence. In panel a) the axisymmetric case is shown, whereas in panels b) and c) the turbulent wave vectors are confined to a cone with the opening angle and , respectively. In all panels, the blue and red lines show the components  ⟨ x ⟩  and  ⟨ y ⟩ , respectively, whereas the black line in panel a) shows the averaged perpendicular displacement.
