HUGS - Hawk-I UDS and GOODS Survey

HUGS (an acronym for Hawk-I UDS and GOODS Survey) is a ultra–deep IR imaging survey executed with the Hawk-I imager at the VLT, that observed in the K and Y bands the UKIDSS Ultra Deep Survey (UDS) and the Great Observatories Origins Deep Survey (GOODS)-South fields covered by the CANDELS survey. The HUGS survey was designed to cover the two CANDELS fields accessible from Paranal that do not have suitably-deep K-band images: a sub-area of UDS and GOODS-S. The depth of the images was chosen to be 0.5mag shallower than obtained with the Wide Field Camera 3 (WFC3/IR) at the Hubble Space Telescope (HST) in H160, as appropriate to match the average H-K color of faint galaxies. In the UDS field deep Y-band images have also been acquired. They are an essential complement to the CANDELS data set, since neither Y098 nor Y105 imaging of this field has been obtained within CANDELS. This release contains deep Y-band images of the UDS field and the extracted source catalogue.
