X-ray spectra of the sources (data points) together with absorbed Γ= 1.9 power-law models (black stepped lines). Both model and data have been divided by the effective area as a function of energy, and the spectra are displayed as E×F_E so that an unabsorbed power law with Γ= 2 would be a horizontal line. When the absorbed Γ= 1.9 power-law model does not provide an acceptable fit to the data, the best alternative model is shown in grey. For XMM J021908.37−044731.4, XMM J021939.22−051133.7 and XMM J094239.79+465005.3 the grey model includes a mekal component, for XMM J083139.11+524206.2, XMM J133026.09+241356.7, XMM J150339.60+101605.6 and XMM J161736.21+122901.5 the grey model includes an unabsorbed power-law component, for XMM J080625.35+244326.0 the grey model has an ionized absorber, and for XMM J122656.53+013125.2 the grey model has a power-law index of Γ= 1.5.
