Notes. For the first and third XMM-Newton observations we considered the spectra of the full exposure, for the second observation we considered the spectra in the time intervals identified with PELT (see Fig. 4). Uncertainty ranges at 90% confidence level are in reported. Gas absorption has been fixed to NH = 5.5  ×  1022 cm−2. Fluxes of the APEC and the Gaussian components are calculated in the 0.3–8.0 keV band; these fluxes are plotted in Fig. 13 as functions of time.
