Notes. ^aThe reduced $\chi^2_{\rm r}$ and degrees of freedom (NDF) correspond to fits of either a power-law (PL) function or broken power-law (BPL) function to the XMM-Newton X-ray data. ^bThe integrated fluxes have the effects of Galactic absorption removed. ^cAll errors from the XMM-Newton fits are quoted at the 90% confidence level.
