a Based on good time interval (with low solar proton flux) and excluding the stellar flare (see Fig. 5).
b Data stands for "fit weight data" and model stands for "fit weight model".
c Fixed at literature value from Monsignori Fossi et al. (1995).
d Based on O VII lines only.
e In the 0.3-10 keV energy interval.
