Fig. 3


The 2006 (top) and 2000 (bottom) XMM-Newton spectra, the best-fit model components, and the complete model shown with thick and thin solid lines, respectively. Both spectra are described by the baseline model that comprises a high-energy X-ray power law with a reflection component and absorption by three layers of low-, moderate- and high-ionization gas as well as a Galactic column. The source is partially covered by WA2 for the 2006 and by WA1 for the 2000 observation. The data from 2006 also require a steep soft excess. The sharp residuals at ~1.85 keV are likely due to calibration uncertainties around the Si K edge.
