\caption{Spectral parameters of 54 XRRs/XRFs. The  models used   are: BAND~= Band function, PL~= powerlaw as  $N$(E)~= $KE^{\Gamma}$, PLE~= powerlaw~$\times$ exponential cutoff as  $N$(E)~= $KE^{\beta_1}\times \exp~(-E/E_0)$, PLA~= absorbed powerlaw  as $N$(E)~= $KE^{\Gamma}\times \exp~(-N_{\rm H}\sigma(E))$. When not given directly, we have derived $\epc =(2+\beta_1)\times \eo$.}\label{tab1}
