Comparison between electron energy spectrograms measured by EAS and MEA 1. Upper panel: time-energy spectrogram of electron count rates measured by EAS and time-shifted to the location of BepiColombo during its second Venus flyby on August 10, 2021, with the superimposed spacecraft potential of SolO measured by RPW Φ_SolO (in black). Lower panel: time-energy spectrogram of electron count rates built with the virtual channel extracted from the MEA 1 3D data products.
