Characteristic energy maps E₀ obtained from the CR(E₀, θ) relationships (see Figs. D.2 and D.3) modeled for the case of an initial mono-energetic electron flux distribution, and from the CR observed during PJ32, at the north (left panel) and south (right panel) poles. Iso-energy lines are defined for values of 1, 5, 10 keV, in steps of 20 keV between 10 and 300 keV, and then in steps of 100 keV between 300 and 900 keV.
