\caption{Spectral fit with a broken power law model ($\Gamma_{\rm soft}$, $\Gamma_{\rm hard}$, 
and $E_{\rm c}$ break point for the energy in keV), 
 including the Galactic ($N^{\rm Gal}_{\rm H}$) and intrinsic ($N^{\rm in}_{\rm H}$)
 absorptions (expressed in 10$^{20}$~cm$^{-1}$).  
The unabsorbed fluxes are expressed in 10$^{-12}$~erg~s$^{-1}$~cm$^{-2}$. 
 In parentheses are reported the luminosities (expressed in 10$^{44}$~erg~s$^{-1}$). 
 The last column reports the flux ratio in the 0.3--2~keV and 0.3--10~keV energy bands. 
 For PG~1114+445, two strong absorption edges are required (see values in Table~\ref{tab:WA}).
