Fitting of the time-integrated spectrum by the broken power law+NUCLEAR+511keV+2.2 MeV model (Lysenko et al. 2019). The component colour codes are given in the panel. The Konus/Wind (KW) data are shown using symbols, where the horizontal dashes indicate the energy range of each data point, while the vertical dashes indicate the corresponding statistical errors. The lower panel shows the fit residual. Adopted from Fig. 3 of Lysenko et al. (2019).
