Number flux of planetary oxygen (a) ions and (b) ENAs precipitating onto the Venusian exobase in the VSE frame. The format of each panel is identical to that of Figure 3(a). (c) Energy spectra of the planetary oxygen ions (solid lines) and ENAs (dashed lines) on the dayside, on the nightside, and on the nightside close to the electric north pole (latitudes from 60^∘ to 90^∘).
