Fig. 7: Modulation of electron flux (Event 2).

From: Direct observations of energy transfer from resonant electrons to whistler-mode waves in magnetosheath of Earth

Fig. 7

The format is the same as that of Fig. 5. Both measurements by Fast Plasma Investigation-Dual Electron Spectrometers and EDI_180 indicate the existence of a dip of electron fluxes at \(\zeta\) of about 90° around Vres. When Bw was about 0.5 nT, electrons around 500 eV exhibited nongyrotropy in the pitch angle (PA) range of around 135°–165° (Supplementary Fig. 9d), this range is consistent with the width of trapping derived by a rough estimation.
