Top: distribution function of the field-line curvature K_∥ and inverse perpendicular reversal scale K_⊥ of the anisotropic field (orange lines). K_iso (black line) corresponds to the field-line curvature of the isotropic field. Vertical lines indicate the rms of the vector fields. Bottom: parallel (circles) and perpendicular (triangles) mean free path as a function of gyroradius normalized by ﹩{K}_{\mathrm{peak}}^{-1}﹩ for isotropic (black) and anisotropic (orange) turbulent fields.
