Peak energy for the differential energy flux of spacecraft electrons, Epeak, SC, (blue dots) and energy for the spectrum break between spacecraft and ambient plasma electrons, Ebreak, (orange dots) is plotted as a function of the electron core temperature Te, core. The black dotted line indicates the mean value of Epeak, SC. The black dashed line shows the model dependency of Ebreak for the case of two Maxwellian populations for mean parameters derived from the dataset, the grey dashed lines show the model shifted by the standard deviation, σmodel, of the difference between the model and Ebreak from the dataset.
