\caption{\label{tab}Fitting parameters of the 0.6$-$11.0~keV combined RGS + EPIC-pn spectrum (centre) and of the 1.4$-$11.0~keV EPIC-pn spectrum (right) of {\saxj}. The continuum was modelled  by a \texttt{diskbb} (DBB), a \texttt{bbodyrad} (BB) and a power law (PL). Errors on each parameter are quoted at the 90\% confidence level, as for the rest of the paper.}
