Summary of background-corrected MagEIS electron flux measurements from Probe-B. Two channels are shown from each unit, LOW (orange labels), M75 (blue), and HIGH (red). The spin-averaged fluxes were obtained when the spacecraft was in close proximity to the magnetic equator, as measured by the ratio of the local magnetic field strength ($B$) to the equatorial field ($B_{eq}$). The data are presented as daily averages in $L$ bins of $0.1L$ width. The long data gaps early in the time interval at $L>3$ are due to the unavailability of histogram data, which are required for the background corrections as detailed in Sect. 3.2.4
