Comparison between the Van Allen Probe B PSD (dashed lines) with the VERB‐4D code results if the W05 electric field model is used (black solid line) and if the Volland, (1973), Stern, (1975), and Maynard and Chen (1975) electric field model is used (blue solid lines) for K = 0.3 G1/2 R E and μ = 0.1 MeV/G (a–c), 2.3 MeV/G (d–f), and 9.9 MeV/G (g–i). Columns correspond to satellite passes beginning at 9:00, 13:30, and 18:00 on 17 March (from left to right). PSD = phase space density.
