Notes. The leftmost column indicates the spectral model used in Xspec. Model 1 is phabs*(BB+pow), model 2 is phabs*pcfabs*pow (phabs is the absorption component, pow the powerlaw, BB the blackbody, and pcfabs the partial covering). We indicated with Γ the power-law photon index, NH the absorption column density in units of 1022 cm-2, f the covering fraction in the partial covering model (the local absorption component is indicated with NHb in units of 1022 cm-2), and kTBB (RBB) the temperature (radius) of the BB component in keV (km). For RBB we considered a source distance of 6.1 kpc (see Sect. 1). For the model that includes the BB component (Model 1), we report both the best fit values obtained with a hotter (kT ~ 1 keV) and colder (kT ~ 0.1 keV) emitting surface. We also reported the normalization constants CMOS1, CMOS2, and CISGRI for the MOS1, MOS2 and ISGRI spectra, respectively (we fixed the EPIC-pn constant to 1 as a reference). The unabsorbed fluxes (units of 10-12 erg/cm2/s) in the 0.5–2 keV, 2–10 keV, and 20–40 keV are indicated in all cases with F0.5−2 keV, F2−10 keV, and F20−40 keV, respectively.
