VIKING - VISTA Kilo-degree Infrared Galaxy Survey

The VIKING survey with VISTA (ESO programme ID 179.A-2004) is a wide area (covering a final area of 1350 sq.degrees), intermediate-depth (5-sigma detection limit J∼21 on Vega system) near-infrared imaging survey, in the five broadband filters Z, Y, J, H, Ks.The sky coverage is at high galactic latitudes, and includes two main stripes ∼ 70 × 10◦ each: one in the South Galactic cap near Dec∼ −30◦, and one near Dec∼0◦ in the North galactic cap; in addition, there are two smaller outrigger patches called GAMA09 and CFHLS-W1. Science goals include z >6.5 quasars, extreme brown dwarfs, and multiwavelength coverage and identifications for a range of other imaging surveys, notably VST-KiDS and Herschel-ATLAS.
