Notes. The model is an absorbed APEC thermal component plus a Gaussian that models the fluorescence at ∼6.4 − 6.6 keV. Ranges at the 90% confidence level are indicated in braces, and in some cases the high limit of temperature uncertainty is not constrained. A value of Z/Z⊙ of 0.54 has been derived from the third exposure (quiescent phase) and used for the best fit of the spectra of the first and second exposures. The 90% confidence level uncertainty of the EWs of the Gaussian line is on the order of 0.1–0.3 keV. Unabsorbed fluxes for the APEC and the Gaussian components are given in the energy band 0.3–8.0 keV, the fluxes at E > 7.11 keV are also listed. X-ray luminosities are calculated from fluxes using a distance of 120 pc.
