Notes. For each fit, the following parameters were kept frozen: NH = 0.4 × 1022 cm-2, Fe/solar = 1, and rbr = 6 Rg. The parameter rbr in the kerrconv model is break radius separating the inner and outer portions of the disk, having emissivity index Index1 and Index2, respectively, which in our fit are constrained to assume the same value, Index. Errors are reported with a 90% confidence. RBB are estimated assuming a distance of 7.7 kpc (Galloway et al. 2008).
