\tablefoot {An emission line (\textit{Cu}) with energy and width fixed at 8.04~keV and 0.01~keV was added to \texttt{FDCUT} and \texttt{NPEX} models. All models include also an absorption like feature at ${\sim}23$~keV for PCA to account for similar residuals seen in Crab spectra (with the line energy and width fixed to those obtained from Crab fits). For \texttt{CompTT} model the $\chi^2$ may be improved by allowing the line parameters to vary (last column). \\
