The XMM-LSS-CFTHLS cluster sample and its cosmological modelling
M. Pierre and the XMM-LSS consortium

Abstract: The current 10 deg2 XMM-LSS-CFHTLS-W1 area possesses a unique deep coverage in X-ray, optical, infrared, UV and radio., We present the construction of the XMM-LSS-CFHTLS-W1 cluster sample. Special attention is drawn to completeness and to the monitoring of selection effects. , We discuss the cosmological modelling of the cluster sample along with known and unknown aspects of the evolution of cluster physics., ,
