\tablefoot{The first line of each modelling provides the best\--fit model parameters of the joint fit.
The second to the sixth line provide only the parameters that were free to vary 
 between the spectra taken different epochs: September 2002 (Chandra observation of 
 low state, second line), May 2003 (high state, third line), November 2005 (deep 
 minimum state, fourth line), May 2007 (low state, fifth line), and November 2007 
 (low state, sixth line).
Explanation of labels: 
 \tablefoottext{a}{the spectral models are described in Table~\ref{Mod};}
 \tablefoottext{b}{equivalent column density;} 
 \tablefoottext{c}{covering fraction;}
  \tablefoottext{d}{ionisation level of absorbing material $\xi=L/nr^{2}$,  as defined in {\em XSPEC};}
\tablefoottext{e}{photon index of power-law continuum;}
 \tablefoottext{f}{fixed;}
 \tablefoottext{g}{normalisation of photon flux at~1~keV;} 
 \tablefoottext{h}{degrees of freedom.}
The best fitted parameters for the ionised reflector, the disk and the
 black hole are provided in Table~\ref{X_FITS_BL}. 
All errors are provided for the 90\% confidence level.}
