Bartels-rotation averages of MPA 40 keV electron and MAGED electron fluxes. (Left) GOES-13 and 1994-084 fluxes, 2011–2017. (Right) GOES-15 and LANL-01A fluxes, 2011–2018. The second-order fits to the MPA and MAGED 40-keV electron fluxes are represented by solid lines. In each panel, the MPA fluxes are also plotted at three times their magnitude in order to distinguish them from the MAGED fluxes at the same energy. (The energy unit is converted from keV to eV to be consistent with the Denton et al., 2015, 2016 model).
