cds-question@unistra.frsurveysgalaxy-clustersredshiftedCounting clusters is one of the methods to constrain cosmological parameters, but has been limited up to now both by the redshift range and by the relatively small sizes of the homogeneously surveyed areas. In order to enlarge publicly available optical cluster catalogs, in particular at high redshift, we have performed a systematic search for clusters of galaxies in the Canada France Hawaii Telescope Legacy Survey (CFHTLS). We considered the deep 2, 3 and 4 CFHTLS Deep fields (each 1x1deg^2^), as well as the wide 1, 3 and 4 CFHTLS Wide fields. We used the Le Phare photometric redshifts for the galaxies detected in these fields with magnitude limits of i'=25 and 23 for the Deep and Wide fields respectively. We then constructed galaxy density maps in photometric redshift bins of 0.1 based on an adaptive kernel technique and detected structures with SExtractor at various detection levels. In order to assess the validity of our cluster detection rates, we applied a similar procedure to galaxies in Millennium simulations. We measured the correlation function of our cluster candidates. We analyzed large scale properties and substructures, including filaments, by applying a minimal spanning tree algorithm both to our data and to the Millennium simulations.2010A&A...509A..81Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/509/A81CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/461/81 : Galaxy clusters in the CFHTLS (Olsen+, 2007)J/A+A/494/845 : Galaxy clusters in the CFHTLS (Grove+, 2009)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/509/A81https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/509/A81http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/509/A81https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/509/A81https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/509/A81http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/509/A81GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/509/A81/tablea (Candidate clusters detected in the D2, D3, D4, W1, W3 and W4 CFHTLS field (tables A1-A6 of the paper))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/509/A81/tablea?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/509/A81/tablea?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/509/A81/tablea?GETtext/xml+votable180.050000true149.69311.96130.0055555555555555565/2687 2856 4419-4422 9198 6/10741-10743 10747 11403 11432 17671 17692-17694 17701 17712-17714 17728 17730 19021 19023 19032 19034-19035 19056-19057 27256 27258-27259 36798 48478-48479 48500-48501https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/509/A81?format=asciiOpticaldefaultJ/A+A/509/A81/tableaCandidate clusters detected in the D2, D3, D4, W1, W3 and W4 CFHTLS field (tables A1-A6 of the paper)FldCFHTLS field name ( D2, D3, D4, W1, W3 or W4)meta.id;obs.fieldcharrecnoRecord number assigned by the VizieR team.
