XMM-Newton serendipitous survey. IV (Barcons+, 2007)
X-ray sources at intermediate fluxes (a few x10-14erg/cm a sky density of ~100deg-2 are responsible for a significant fraction of the cosmic X-ray background at various energies below 10keV. The aim of this paper is to provide an unbiased and quantitative description of the X-ray source population at these fluxes and in various X-ray energy bands
