Notes. The model consists of const*phabs*(bbody + nthComp + rdblur*highecut*reflionx). The inclination angle is fixed at 37°, while the Fe/sol ratio is left free to vary or is fixed to 2. Here we show the best fit parameters we obtain for the BeppoSAX spectrum. A few parameters of the continuum got different best fit values for the nonsimultaneous XMM-Newton and RXTE spectra, as detailed in Table 3.
