Notes. Unabsorbed X-ray flux and luminosity, in units of 10−13 ergs s−1 cm−2 and 1031 ergs s−1, respectively, are calculated in the 0.3–50 keV energy band for the optically thin thermal components and in the 1 eV–10 keV band for the optically thick thermal component. Elemental abundances are quoted in units of abundances from Wilms et al. (2000). Luminosity, size of the blackbody emitting region, and are determined assuming a distance of 806 pc.
