Notes. The fits shown in this table were performed separately for the 2000 and 2017 data sets. The fixed parameters in the model are β1 = 5, β2 = 3, Rbr = 4 Rg, Rin = 1 (RISCO), and Rout = 400 Rg (see text for details). NH is given in units of 1022 cm−2, the power law normalization factor with the units of photons keV−1 cm−2 s−1 at 1 keV, the total flux for each energy range in units of 10−11 erg cm−2 s−1, ξ′ in units of erg cm s−1, AFe in solar units, and h in Rg.
Absorption-corrected fluxes were estimated for the following ranges: 0.23−10 keV (2000) and 0.7−10 keV (2011). For the latter, the total flux is the average of the XIS cameras. For the 2017 spectrum, separate calculations were made for the ranges: 0.23−10 keV(XMM)/3−50 keV(NuSTAR). The total flux of the 3−50 keV range is the average value of the FPM detectors.
