Figure 3 H⁺ ion velocity distribution functions at different geocentric altitudes in the polar wind (left panel) and auroral (right panel) regions. f(H⁺) Is represented by equal value contours in the normalized velocity plane, where . The contour levels decrease successively by a factor e^1/2 from the maximum.
