Abstract:
The VIKING survey with VISTA (ESO programme ID 179.A-2004) is a wide
area (eventually 1500 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 planned sky coverage is
at high galactic latitudes, and includes two main stripes 70x10°2
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.
This first public data release of data taken between the 12th of
November 2009 and the 13th of February 2011 includes 151 tiles with
complete coverage in all five VIKING filters (55 in GAMA09/12/14, 91
in SGP and 5 in CFHLS-W1) i.e. 226 square degrees, and includes
approximately 14,773,385 total sources (including low-reliability
single-band detections) and the imaging and source lists total
314.4GB. The coverage in each of the five sub-areas is not completely
contiguous but any inter-tile gaps are relatively small.
More details can be found in the accompanying documentation:

Data origin:
Data originate from the ESO Science Archive Facility and went through
the Phase 3 content validation process.

--------------------------------------------------------------------------------
Note (1): We recommend that users should restrict their analysis to objects with
zppErrBits, yppErrBits, etc<255 at all times and zppErrBits=0 if they require
the most reliable subset of the sources. Values of zppErrBits=16 indicate that
the source was deblended, zppErrBits=64 that at least one bad pixel was within
the default aperture and zppErrBits=128 that the source was low confidence
within the default aperture."
