(Top) Pitch angle distribution classification for $\sim 450\text{keV}$ electrons from MagEIS-A. At the outer portion of the inner belt, electrons associated with inward radial transport are largely peaked at ${90}^{\circ }$ (green), while in the heart of the inner belt the distributions have a local minimum at ${90}^{\circ }$ (blue). The “cap” or “flat-top” distributions (red) are associated with rapid scattering by waves in the slot region. (Bottom) Spin-averaged flux of $\sim 450$ electrons from MagEIS-A. From Zhao et al.
