Notes. For the top section the units are, from left to right, 10−6phcm−2 s−1 keV−1, 1, and 10−8 erg cm−2 s−1 for the fluxes in the bands 514–850, 850–1813, 1813–3283, 3283–8000, and 514–8000 keV, respectively. Background systematics are estimated for the flux extraction (bottom section) in units of 10−6 ph cm−2 s−1 keV−1 sr−1. The normalisation for the solid angle in this analysis is 2.43 sr. The line in bold corresponds to the best-fitting model.
