Example of the event analysis. Panel (a) depicts the spatial distribution of the satellites in the heliospheric equatorial plane on March 21, 2022. Panels (b)–(d) illustrate the temporal evolution of the proton flux for three satellites in various energy ranges. Panels (e) and (f) present the spectra derived from the peak time of each energy and event-integrated period (shadow area in panels (b)–(d)), respectively. The light lines correspond to the original data sourced from mission websites, and the dark lines represent data that we interpolated to the four energy ranges defined in this analysis.
