\caption{Phase-resolved spectral analysis. We used the CTT model.
         All continuum and normalisation parameters were left free.
	 A few parameters were fixed as for the average spectrum
	 (see Table~\ref{TabSpec}): $N_{\tty{H}}^{\tty{gal}}=1.5\times10^{22}\ \unit{cm}{-2}$,
	 $kT_{{\rm soft}}=0.5\ {\rm keV}$, $kT_{0}=0.1\ {\rm keV}$.
	 Only pn data were used for the phase-resolved spectral analysis.
