VIKING

• VIKING is the VISTA Kilo-degree Infrared Galaxy survey.

• overing the 1500 deg2 of the VST-KIDS survey in the 5 broadband filters Z,Y,J,H,Ks. Combined with KIDS
• 9-band optical-IR survey with depth approximately 2 mag deeper than Sloan and 1.4 mag deeper than UKIDSS-LAS.

VIKING 的z波段大概比SDSS的r波段深一等。

• In area and depth, the KIDS+VIKING survey is a natural intermediate between the shallower SDSS, VSTATLAS and UKIDSS-LAS, and the deeper 30 deg2 surveys.
• Some part of it is observable year-round from Paranal, providing a rich source of targets for VLT follow up.
