cds-question@unistra.frgalaxy-clustersredshiftedWe apply a matched-filter cluster detection algorithm to the Canada-France-Hawaii Telescope Legacy Survey (CFHTLS) i-band data for the Deep-1, Deep-2, Deep-3 and Deep-4 fields covering a total of 4 square degrees. To test the implemented procedure we carry out simulations for assessing the frequency of noise peaks as well as estimate the recovery efficiency. We estimate that up to z~0.7 the catalogue is essentially complete for clusters of richness class R>~1. The recovered redshifts are in general overestimated by dz=0.1 with a scatter of sigma_dz_~0.1, except at redshifts z>~1 where the estimated redshifts are systematically underestimated. The constructed cluster candidate catalogue contains 162 detections over an effective area of 3.112 square degrees corresponding to a density of ~52.1 per square degree. The median estimated redshift of the candidates is z=0.6. The estimated noise frequency is 16.9+/-5.4 detections per square degree. From visual inspection we identify systems that show a clear concentration of galaxies with similar colour. These systems have a density of ~20 per square degree.2007A&A...461...81Ohttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/461/81CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/317 : The CFHTLS Survey (T0007) (Hudelot+ 2012)J/ApJ/633/630 : Low-mass stars in CFHTLS (Willott+, 2005)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/461/81https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/461/81http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/461/81https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/461/81https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/461/81http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/461/81GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/461/81/table3 (Cluster candidate parameters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/461/81/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/461/81/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/461/81/table3?GETtext/xml+votable180.050000true36.042917-4.3279720.0055555555555555566/11403 11424-11425 11427 17683 17686 17689 17692 27256 27258-27259 48478-48479 48500-48501https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/461/81?format=asciiOpticaldefaultJ/A+A/461/81/table3Cluster candidate parametersrecnoRecord number assigned by the VizieR team.
