We analyze X-ray sources detected over 4.2 pseudo-contiguous sq. deg. in the0.5-2 keV and 2-10 keV bands down to fluxes of 2x10^{-15} and 8x10^{-15}erg/s/cm^2 respectively, as part of the XMM Large Scale Structure Survey. ThelogN-logS in both bands shows a steep slope at bright fluxes, but agrees wellwith other determinations below ~2x10^{-14} erg/s/cm^2. The detected sourcesresolve close to 30 per cent of the X-ray background in the 2-10 keV band. Westudy the two-point angular clustering of point sources using nearestneighbours and correlation function statistics and find a weak, positive signalfor ~1130 sources in the 0.5-2 keV band, but no correlation for ~400 sources inthe 2-10 keV band below scales of 100 arcsec. A sub-sample of ~200 faintsources with hard X-ray count ratios, that is likely to be dominated byobscured AGN, does show a positive signal with the data allowing for a largescaling of the angular correlation length, but only at the ~2 (3) sigma level,based on re-sampling (Poisson) statistics. We discuss possible implications andemphasize the importance of wider, complete surveys in order to fullyunderstand the large scale structure of the X-ray sky.
