Illustration of the procedure applied to remove the secondary electron emission contribution from a complete electron energy spectrum measured by MEA 1 on March 11, 2022, at 19:39:40 UTC. The red line corresponds to the original count rate, the brown stars are a Maxwellian fit of the original count rate. The magenta dotted lines represent the residuals at low and high energies when the Maxwellian fit has been subtracted from the original count rates. Finally, the brown line shows the reconstructed corrected count rate.
