cds-question@unistra.frsurveysinfrared-photometryvisible-astronomyphotometryWe describe the final product of the North Celestial Cap Survey (NCCS) - the optical-UV-IR merged catalogue for the region within 10{deg} of the North Celestial Pole. The North Celestial Cap (NCC) region at {delta}>=80{deg} is poorly covered by modern CCD-based surveys. The optical part of the survey was observed in V, R and I with the Wide-field Infrared Survey Explorer (WISE) Observatory telescopes and was merged with GALEX UV and WISE IR data, producing the catalogue. More than four million objects were observed in at least one optical band. The final catalogue contains ~1.6 million sources observed in all three optical bands, of which some 1.4 million have WISE counterparts and ~300000 have GALEX counterparts. The astrometric accuracy of the optical NCCS data, derived from a comparison with the UCAC3 catalogue, is better than 0.2-arcsec and the photometry, when compared with Sloan Digital Sky Survey, is good to ~0.15mag for sources brighter than V=20.3, R=21.0 and I=19.2mag. The Sloan Digital Sky Survey point-extended source separation is reproduced with >92 per cent efficiency.2014MNRAS.443..725Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/443/725CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/311 : WISE All-Sky Data Release (Cutri+ 2012)II/312 : GALEX-DR5 (GR5) sources from AIS and MIS (Bianchi+ 2011)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/443/725https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/443/725http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/443/725https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/443/725https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/443/725http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/443/725GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/443/725/catalog (*Full optical uncleaned NCCS catalogue (catalog_final.dat))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/443/725/catalog?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/443/725/catalog?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/443/725/catalog?GETtext/xml+votable180.050000true130.1238386.993910.005555555555555556Cone search capability for table J/MNRAS/443/725/cleancat (Cleaned and matched optical-UV-IR catalogue (catalog_clean_wise_galex.dat))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/443/725/cleancat?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/443/725/cleancat?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/443/725/cleancat?GETtext/xml+votable180.050000true130.1238386.993910.0055555555555555563/255 4/251 253-255 509-511 759 765-767 1019 5/989-991 1009-1011 2013-2015 2029-2031 2033-2035 3031 3035 3053-3055 3057-3059 4059 4061-4063 4071 4075 6/3933-3935 3949-3951 3953-3955 3997-3999 4007 4013-4015 4033-4035 8029-8031 8045-8047 8049-8051 8093-8095 8109-8111 8113-8115 8129-8131 12123 12135 12189-12191 12205-12207 12209-12211 12225-12227 16221-16223 16231 16235 16241-16243 16279 16283 16293-16295 16297 162998.157980699529898e-21 1.4134638842407062e-18https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/443/725?format=asciiOpticalInfrareddefaultJ/MNRAS/443/725/catalog*Full optical uncleaned NCCS catalogue (catalog_final.dat)Seq[1/4102998] Catalogue object name (1)meta.id;meta.mainintprimaryindexedSt[1/3] Object status (G1)meta.idintRAJ2000Right ascension (J2000.0)degpos.eq.ra;meta.mainindexede_RAJ2000[0/0.7] rms uncertainty on RAdegarcsecstat.error;pos.eq.rafloatDEJ2000Declination (J2000.0)degpos.eq.dec;meta.mainindexede_DEJ2000[0/0.9] rms uncertainty on DEdegarcsecstat.error;pos.eq.decfloatVmag?
