\caption{Spectral analysis. The EPIC and ISGRI spectra were fitted together.
         Two models in {\tt Xspec} were selected to fit the data. Model CPL is
         {\tt constant*wabs(bbody+vphabs(cutoffpl+gaussian))}
         and model CTT is
           {\tt constant*wabs(bbody+vphabs} {\tt (compTT+gaussian))}.
         The galactic absorption $N_{\tty{H}}^{\tty{gal}}$ was fixed. The errors
         are calculated at the~90\% confidence level.
