cds-question@unistra.frx-ray-sourcesgalaxiesphotometryredshiftedWe present the X-ray source catalogues for the XMM surveys of the 3-h and 14-h (also known as the Groth Strip) Canada-France Redshift Survey fields (0.5-10keV flux range ~2x10^-15^-10^-13^erg/cm^2^/s). We use a subset of the XMM sources, which have Chandra positions, to determine the best method of obtaining optical identifications of sources with only XMM positions. We find optical identifications for 79 per cent of the XMM sources for which there are deep optical images. The sources without optical identifications are likely to be optically fainter and have higher redshifts than the sources with identifications. We have estimated 'photometric redshifts' for the identified sources, calibrating our method using ~200 galaxies in the fields with spectroscopic redshifts. We find that the redshift distribution has a strong peak at z~0.7.2004MNRAS.350..785Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/350/785CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/xmm : XMM-Newton Observation Log (XMM-Newton SOC, 2002)VII/225 : The Canada-France Redshift Survey (CFRS) (Lilly+, 1995)J/ApJ/464/79 : CFRS XI: High-z field galaxies morphology (Schade+ 1996)J/ApJ/481/49 : CFRS XIV.
