Notes. Best-fit parameters of the three hot components. The symbol NH represents the hydrogen column density in 1021 cm−2 and kT represents the temperature in eV. The temperature of the neutral gas component (hot # 1) is frozen to the minimum value in order to produce neutral species only. This is noted with the symbol f.
