Notes. The three Gaussian functions model the Fe Kα and Kβ narrow emission lines (with σ = 0) and the broad Fe K emission line. The Fe Kβ emission line was fixed in energy (E_Kβ = 7.06 keV) and in normalization (imposed equal to 0.15 times the Kα line normalization). Γ is the power-law photon index; the power-law normalization C_Γ is the number of photons keV^-1  cm^-2  s^-1 at 1 keV; the line normalization parameters C_Kα and C_br are the integrated number of photons cm^-2  s^-1 in the line; σ_br is the line width expressed in keV; EqW is the line equivalent width expressed in eV; the flux F, evaluated between 3 and 10 keV, is given in units of erg  cm^-2  s^-1. For the summed spectra, the results of a XIS (above 3 keV) + PIN fit are reported as well (last line): the R_pexrav parameter represents the pexrav reflection scaling factor (see Sect. 3.3).
