Fig. 6.

(a) Magnetospheric field lines of a zonal quadrupole configuration, (b) particle impact regions (proton energy 4 GeV, g 02 = 24500 nT), (c) cutoff angles (the upper branch of the curve belongs to ϑcutoff1, the lower one to ϑcutoff2) and (d) the impact area. Particle impact at ϑcutoff1 ≤ ϕ ≤ 90° and 0° ≤ ϕ ≤ ϕcutoff2.
