Top: count rates of the E150 and the P4GM coincidence counters during an automatic ring switch event of the instrument. Bottom left and middle: energy deposition in the A detector versus B detector during the “ring off” and “ring on” periods, respectively. The time intervals are highlighted in the top panel, with the “ring on” period in green and the “ring off” period in red. The blue curved line shows the highest measured energy used in this data product. The horizontal lines labeled with A1 and A4 indicate the energy thresholds used by the instrument to distinguish between protons, electrons, and helium particles. Bottom right panel: energy-loss distribution in SSD-B of all entries inside the corresponding boxes in the middle panel.
