Description
The COSMOS survey is a multiwavelength survey aimed to study the evolution of galaxies, AGN and large scale structures. Within this survey XMM-COSMOS a powerful tool to detect AGN and galaxy clusters. The XMM-COSMOS is a deep X-ray survey over the full 2deg^2^ of the COSMOS area. It consists of 55 XMM-Newton pointings for a total exposure of ~1.5Ms with an average vignetting-corrected depth of 40ks across the field of view and a sky coverage of 2.13deg^2^. The analysis was performed using the XMM-SAS data analysis package in the 0.5-2keV, 2-10keV and 5-10keV energy bands. Source detection has been performed using a maximum likelihood technique especially designed for raster scan surveys. The completeness of the catalogue as well as logN-logS and source density maps have been calibrated using Monte Carlo simulations.
