Spectrum of the analysed region between 0.5 and 8 MeV. The orange data points show the extracted fluxes from the energy-dependent IC template δ₁ = δ₂ = 0.5, and the fuchsia points a re-binning to a minimum signal-to-noise ratio of 6. The fitted power-law spectrum (F_0.5–8.0 = (5.7 ± 0.8) × 10⁻⁸ ergcm² s⁻¹ α = −1.39 ± 0.09) is shown with its 68.3, 95.4, and 99.7 percentile bands in violet, and the fitted cutoff power law with E_C = 4.9 ± 1.4 MeV in red. We compare the fluxes of this work with historic measurements by COMPTEL (green; Strong et al. 1999).
