Middle-energy electron anisotropies in the auroral region

Field-aligned anisotropic electron distribution functions of <i>T</i><sub>&#x2225;</sub> > <i>T</i><sub>&#x22A5;</sub> type are observed on auroral field lines at both low and high altitudes. We show that typically the anisotropy is limit...
