This is the deepest observation carried out as yet with XMM-Newton with more that 600 ks of good EPIC-pn data.There are spectra with good signal to noise (>500 source counts) for all objects down to 0.2 - 12 keV fluxes of 5 x 10<sup>-15</sup> erg/cm<sup>2</sup>/s (the flux limit is 6 x 10<sup>-16</sup> erg/cm<sup>2</sup>/s in the 0.5 - 2.0 and 2 - 10 keV bands). At the time of the analysis, the authors had optical spectroscopic identifications for 60% of the sources, 46 being optical type-1 AGN and 28 optical type-2 AGN. Using a single power law model, their sources' average spectral slope hardens at faint 0.5 - 2 keV fluxes but not at faint 2 - 10 keV fluxes.
