Bartels-rotation averages of MPA 40 keV ion and MAGPD proton fluxes, uncorrected (top) and corrected (bottom). (Left) GOES-13 and 1994-084 fluxes and fits, 2011–2017. (Right) GOES-15 and LANL-01A fluxes and fits, 2011–2018. The second-order fits to the fluxes are indicated by solid lines in both the uncorrected (top) and corrected (bottom) plots; the GOES-13 fits are to the data with the “day 1” correction applied. (The energy unit is converted from keV to eV to be consistent with the Denton et al., 2015, 2016 model).
