Notes:\\
$^a$~The electron temperature is calculated for the best-fit model (i.e., not free parameters).\\
Model applied in {\tt XSPEC} notations: {\sc constant}*{\sc wabs}*({\sc diskpn}+{\sc gaussian}+{\sc eqpair}) or {\sc constant}*{\sc wabs}*({\sc diskbb}+{\sc gaussian}+{\sc compps}) with $N_{\rm H}$ fixed to 6~$\times$~10$^{21}$~cm$^{-2}$ and $kT_{\rm 0}$ value tied to disc $kT_{\rm in}$. Errors are at 90$\%$ confidence level ($\Delta$\ki~=~2.7).
