Best-fitting parameters of the absorbed cutoff power-law, high-energy cutoff power-law, COMPTT, and COMPMAG models for the joint JEM-X plus IBIS/ISGRI spectra (see Figs. 4 and 5).

Parameter Cutoff power-law Power-law with

(d.o.f.) 1.195 (100) 1.009 (100)

Notes. For COMPTT model kTseed corresponds to kTw. For COMPMAG model kTseed corresponds to kTbb. We assumed a free-fall velocity profile for the accreting matter (η = 0.5), β0 = 0.05, r0 = 0.25, A = 1. Listed uncertainties are at the 90% confidence level.
