Fig. 11From: Medium-energy particle experiments–ion mass analyzer (MEP-i) onboard ERG (Arase)One-day plot of the MEP-i observation on 4 August 2017; a Dst index, b–g energy/charge (E/q)-time spectrograms of H+, He++, He+, O++, O+, and O2 + obtained in the Normal mode, and h E/q-time spectrogram of all ion species in the TOF mode. The colors indicate the energy differential flux (keV/cm2 sr keV s)Back to article page
