First Release of VST Public Survey ATLAS Imaging Data

28 Novembre 2013

ATLAS is a ugriz imaging survey targeting ~4500 square degrees of the southern sky with the VLT Survey Telescope (VST). Data products resulting from the first release of the ATLAS public survey are now available via the dedicated Phase 3 query interface at the ESO Science Archive Facility.

This data release consists of the stacked reduced images and associated source lists from the start of observations in August 2011 to end September 2012 under ESO programme ID 177.A-3011. The imaging data comprise the combination of the two individual pawprint images which go to make an ATLAS stacked pawprint in each field. The passbands covered are SDSS ugriz reaching approximately the same depth (r~22) as the SDSS survey in the northern hemisphere. The data release comprises a total of 32 031 data files occupying ~3TB in its default Rice compression. The total area covered is ~1000 square degrees.

The ATLAS public survey data release is accompanied by a comprehensive description.
