Table 1:

Fits of the ISGRI and *Chandra* data with the COMPTB model.
Parameter	Value
Blackbody temperature ( $kT_{\rm s}$ )	0.72 keV
Index of Seed photons ( $\gamma$ )	0.95
Energy index of Compton spec. ( $\alpha$ )	0.36
Efficiency of bulk over thermal Compt. ( $\delta$ )	2.32
Electron temperature ( $kT_{\rm e}$ )	24.6 keV
Ilumination factor (log(A))	-2.3
Normalization ( $C_{\rm N}$ ) $\dagger$	$1.18\times10^{-2}$
$\chi^{2}$ /d.o.f.	166.74 / 248

Notes. $\dagger$ Normalization of the seed-photon spectrum defined as L₃₉/D₁₀², where L₃₉ is its luminosity in units of $10^{39}~\rm {erg~s^{-1}}$ , and D₁₀ is the distance to the source in units of 10 kpc.
