Table 3

Parameters left free to vary between XMM-Newton, BeppoSAX, and RXTE in the hard state.

Parameter XMM BeppoSAX RXTE

NH   (× 1022   cm-2) 2.0 ± 0.3 1.9 ± 0.1 B
kTbb (keV) B
Normbb (× 10-3) 2.6 ± 0.5 2.0 ± 0.4 B
Γ B 1.84 ± 0.01
kTe (keV) B

Notes. The complete model is given in Table 8. B: corresponding parameter is fixed to have the same value as in the BeppoSAX spectrum. kTbb, Normbb: temperature and normalization of the blackbody component. Γ, kTe: photon index and electron temperature of the nthComp component.
