a Variation of the pitch angle at the center of the field-of-view for sensor channels of the MEP-e during one spin period of 8 s under the assumed condition. Schematics shown in the upper panel represent the FOV of each sensor channel every 2 s, where the color of rectangles corresponds to those of plotted lines. b Energy range measured by MEP-e during one spin period, where 16 energy steps are swept every 0.25 s. c Estimated number of counts measured by the MEP-e during one spin period
