N2 - We describe the final product of the North Celestial Cap Survey (NCCS) - the optical-UV-IR merged catalogue for the region within 10° of theNorth Celestial Pole. TheNorth Celestial Cap (NCC) region at δ ≥ 80° 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 9501.6 million sources observed in all three optical bands, of which some 1.4 million have WISE counterparts and 950300 000 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 9500.15 mag for sources brighter than V = 20.3, R = 21.0 and I = 19.2 mag. The Sloan Digital Sky Survey point-extended source separation is reproduced with >92 per cent efficiency.
