Figure 4. Differential energy spectra of electrons (red) and
gamma rays (black) were registered on May 24, 2021
In Table 2 we post the parameters of the energy spectra of both species
for 4 minutes of the maximum TGE flux. In second and third columns –
the integral energy spectrum of both fluxes (started from 7 MeV); in
fourth – the electron-to-gamma ray ratio; in the fifth and sixth –
maximal energies of differential energy spectra for both species; and in
the last – an approximate estimate of termination height of the strong
accelerating electric field (according to the algorithm from
Chilingarian et al., 2021d).
