Theoretical SED (top) and XSPEC spectral fits (bottom) for the five canonical spectral states computed in Fig. 9. It can be seen that hard state spectra are always dominated by the comptonization of soft photons, mostly due to local Bremsstrahlung and cold photons from the outer SAD. The white area in the theoretical SED corresponds to the observationally relevant 3–200 keV energy band. The value of the spectral index Γ is shown for each state, with its errors.
