Notes. From top to bottom: the spectral index (ΓX), the rest-frame 2−10 keV flux (in units of 10−11 ergs s−1 cm−2), the energy of the Gaussian emission lines (in units of keV), with their normalisation (in units of 10−6 photons cm−2 s−1). In the XMM-Newton observation it was necessary to include a thermal component “mekal”, accounting for the excess in the soft band at ∼2 keV, likely produced by hot diffuse gas. The plasma temperature of the “mekal” component is in units of keV, while the normalisation is in units of 10−3 photons cm2 s−1.
