Table 6: Best-fit parameter values for a wabs $_{{\rm ISM}}$*wind*(mekal+power) model for the combined EPIC-MOS data, EPIC-pn, and the three EPIC spectra together. The ISM absorption component is frozen at 0.58 $\times $ 1022 cm-2. The local absorption column accounts for the ionization of the wind, with $N_{\rm W}$ expressed in cm-2. The upper and lower parts of the table refer to the first and second observation respectively. For the power law component, the normalization parameter (Norm2) corresponds to the photon flux at 1 keV. The error bars represent the 1-$\sigma $ confidence interval.
