$^a$ Based on good time interval (with low solar proton flux) and excluding the stellar flare (see Fig.~\ref{f5}).\\
$^b$ Data stands for "fit weight data" and model stands for "fit weight model".\\
$^c$ Fixed at literature value from Monsignori Fossi et al. (\cite{Monsignori95}).\\
$^d$ Based on O~VII lines only.\\
$^e$ In the 0.3--10 keV energy interval.
