VISTA VIKING Release of Images, Source Lists and Multi-band Catalogue

Published: 22 Sep 2017

This third data release from the VISTA Kilo-degree Infrared Galaxy Public Survey VIKING of images, source lists and a catalogue covers all of the highest quality data (images and single-band source lists) taken from November 2009 to March 2015. The release contains 736 VISTA images, of which 662 have coverage in all five VIKING near-infrared filters, 647 with deep co-adds in J, and an additional 74 with at least two filters. These 736 fields cover a total area of 1104 square degrees.

VIKING is a wide area (final coverage about 1350 sq. degrees), intermediate depth (5σ detection limit J~21 Vega), near-infrared imaging survey in five broadband filters Z, Y, J, H, Ks. The sky coverage has maximum overlap with the Kilo-Degree Survey KiDS in the optical bands.

The aperture matched multi-band catalogue in the third release includes a total of about 74 million sources, with magnitudes, colours and additional parameters providing information on the nature of each source detection. These data can be browsed and downloaded from the ESO Science Archive using the Phase 3 query form. More information about this data release is available in the associated release description.
