As in Fig. 10, but showing the energy in nonthermal electrons normalized by the total heating requirements, E_nth/E_h, vs. peak GOES flux as derived by E+12, IC14, and WM16. The energy required to generate and sustain the hot flare component is approximated by adding the peak thermal energy and the radiative losses, E_th + E_rad, for E+12 and IC14, while it is derived from a time integration of the thermal energy change rate plus the radiative and conductive energy loss rates for WM16.
