Notes. The first part of the Table presents fits with a common absorbing column in front of the soft and hard components, whereas the second part shows results for separate absorbing column densities. In all cases the interstellar column (wabsism) was fixed to 1. × 1022 cm-2 (see Sect. 3) and abundances set to solar. “Unabsorbed” fluxes are corrected for the interstellar column only. Errors (found using the “error” command for the spectral parameters and the “flux err” command for the fluxes) correspond to 1σ; whenever errors are asymmetric, the largest value is provided here. Fluxes are expressed in the 0.5−10.0 keV band. The NH2 value for the XMM-1 fit is basically unconstrained.
