cds-question@unistra.frsurveysgalaxy-clustersredshiftedWe investigate the gain of added leverage and completeness of the constructed cluster catalogue, of applying the matched-filter detection algorithm to multiple passbands. In particular, we investigate the gain from having both i'- and z'-band data available when searching for galaxy clusters at z>~1. We applied a matched filter detection method to the CFHTLS r'- and z'-band data of the four Deep fields and compared the cluster catalogues with the one extracted from the i'-band data presented in a previous paper. We also applied the matched filter to the Deep fields but with the limiting magnitudes appropriate for the much larger Wide survey in order to understand the best combination of i'- and z'-band depth for the most efficient cluster searches based on this algorithm.2009A&A...494..845Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/494/845CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/633/630 : Low-mass stars found in CFHTLS (Willott+, 2005)J/A+A/461/81 : Galaxy clusters in the CFHTLS (Olsen+, 2007)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/494/845https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/494/845http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/494/845https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/494/845https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/494/845http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/494/845GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/494/845/table4 (Cluster candidate parameters for detections in r'-band)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/494/845/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/494/845/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/494/845/table4?GETtext/xml+votable180.050000true36.025833-4.3241110.005555555555555556Cone search capability for table J/A+A/494/845/table5 (Cluster candidate parameters for detections in z'-band)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/494/845/table5?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/494/845/table5?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/494/845/table5?GETtext/xml+votable180.050000true36.042917-4.3254170.0055555555555555565/2856 6814 6/17683 17686 17689 17692 48478-48479 48500-48501https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/494/845?format=asciiOpticaldefaultJ/A+A/494/845/table4Cluster candidate parameters for detections in r'-bandrecnoRecord number assigned by the VizieR team.
