cds-question@unistra.frsurveysvisible-astronomysloan-photometryCanada and France joined a large fraction (~50%) of their dark and grey telescope time from mid-2003 to early 2009 for a large project, the Canada-France-Hawaii Telescope Legacy Survey (CFHTLS). The data acquisition and calibration has been a major undertaking for the Canadian and French communities: more than 2300 hours over 5 years (an equivalent of 450 nights) have been devoted to the survey using the wide field optical imaging camera MegaCam, a 1{deg}x1{deg} field of view 340 Megapixel camera. The CFHTLS comprises 2 components: "CFHTLS Deep", 4 independent 1deg^2^ MegaCam pointing, and "CFHT Wide" comprising 171 MegaCam pointings covering ~155deg^2^ in 4 contiguous independent patches. All areas are located far from the galactic plane, and their central positions are: -------------------------------------------------- Field RA (J2000) Dec Galactic position -------------------------------------------------- W1 02:18 -07:00 172.468 -61.242 W2 08:54 -04:15 232.067 +24.743 W3 14:17:54 +54:30:31 098.850 +58.390 W4 22:13:18 +01:19 063.243 -42.511 D1 02:25:59 -04:29:40 171.993 -58.054 D2 10:00:28 +02:23:30 236.616 +42.227 D3 14:19:27 +52:40:56 096.227 +59.642 D4 22:15:31 -17:43:56 039.271 -52.925 -------------------------------------------------- This final release of the CFHTLS benefits greatly from vastly improved flat-fielding and photometric calibration techniques developed by the Supernovae Legacy Survey (SNLS) team and CFHT which allows us to significantly improve the precision of our photometric calibration compared to previous releases. The astrometric accuracy reaches 0.02arcsec internal and 0.2arcsec external. The set of filters used for the survey are close to the SDSS filter set; their characteristics and a comparison to SDSS can be found at http://www3.cadc-ccda.hia-iha.nrc-cnrc.gc.ca/megapipe/docs/filters.html Please ee the documentation file "T0007-doc.pdf" for details concerning this T0007 release.2012yCat.2317....0Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/II/317CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=II/317https://vizier.iucaa.in/viz-bin/VizieR-2?-source=II/317http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=II/317https://vizier.cds.unistra.fr/viz-bin/votable?-source=II/317https://vizier.iucaa.in/viz-bin/votable?-source=II/317http://vizieridia.saao.ac.za/viz-bin/votable?-source=II/317GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table II/317/cfhtls_w (the CFHTLS Wide Survey (out of 35,651,677 sources))https://vizier.cds.unistra.fr/viz-bin/conesearch/II/317/cfhtls_w?https://vizier.iucaa.in/viz-bin/conesearch/II/317/cfhtls_w?http://vizieridia.saao.ac.za/viz-bin/conesearch/II/317/cfhtls_w?GETtext/xml+votable180.050000true214.66783151.2152870.005555555555555556Cone search capability for table II/317/cfhtls_d (the CFHTLS Deep Survey (out of 2,293,851 sources))https://vizier.cds.unistra.fr/viz-bin/conesearch/II/317/cfhtls_d?https://vizier.iucaa.in/viz-bin/conesearch/II/317/cfhtls_d?http://vizieridia.saao.ac.za/viz-bin/conesearch/II/317/cfhtls_d?GETtext/xml+votable180.050000true215.52605452.1810760.0055555555555555564/714 1104 1191 2298 2559 5/2685-2687 2850-2851 2854 2860-2862 2944-2945 4372-4373 4375 4420-4422 4424-4425 4758-4759 5460 9151 9198 10230 10233 10235 6/10719 10739 11092-11093 11395 11398-11399 11410 11422-11423 11452 11488 11785 11788 11792 17496-17497 17499 17524-17525 17527 17692-17694 17704-17705 17707-17710 17712-17714 17728 17730 19021 19023 19025-19028 19030-19031 19047 19053 19153 19156-19158 19208 19210 19232 19240 19242 21829 21844 27298 27304 36599 36603 36747 36750-36751 36784 36786-36787 36796 36798-36799 40909-40911 40914 40926 40929 40931 40937https://cdsarc.cds.unistra.fr/viz-bin/moc/II/317?format=asciiOpticaldefaultII/317/cfhtls_wthe CFHTLS Wide Survey (out of 35,651,677 sources)recnoRecord number assigned by the VizieR team.
