Table 2: Results of the fits to the X-ray spectra. The table gives the best fit values for the hydrogen column density $N_{\rm H}$ and the plasma temperature $T_{\rm X}$ with the associated $1\sigma$ uncertainties, the intrinsic extinction corrected X-ray luminosity integrated over the [0.2-10] keV band, and the fit statistic $\chi ^2/\nu$ .
