Ultra-deep Ks-band imaging data of the UDS and GOODS-South fields released

Published: 29 Sep 2014

The HAWK-I Ultra Deep Survey and GOODS Survey is a new ultra-deep near-IR imaging survey executed with Hawk-I at the VLT lead by A. Fontana as principal investigator. It was designed to cover the two CANDELS (http://candels.ucolick.org) extragalactic fields accessible from Paranal that do not have suitably-deep K-band images: a sub area of UDS and GOODS-South. It delivers the deepest, highest quality images ever collected in the K-band. Deep Y-band images in the UDS field have also been acquired. The UDS field is covered to a limit of Ks=27.3 (at 1 sigma) and the GOODS-South data reach slightly deeper/shallower limits (Ks=27.8).

Data are grouped in three distinct collections: HUGS_GOODSS_K, HUGS_UDS_K and HUGS_UDS_Y, each of them containing the mosaics and a source catalogue. Images can be queried and downloaded from the ESO Science Archive Facility with the three single-band catalogues being accessible from ESO's dedicated catalogue facility query interface (www.eso.org/qi).
