Abstract

The OmegaCAM wide-field optical imager is the sole instrument on the VLT Survey Telescope at ESO’s Paranal Observatory. The instrument, as well as the telescope, have been designed for surveys with very good, natural seeing-limited image quality over a 1 square degree field. OmegaCAM was commissioned in 2011 and has been observing three ESO Public Surveys in parallel since October 15, 2011. We use the Astro-WISE information system to monitor the calibration of the observatory and to produce the Kilo Degree Survey (KiDS). Here we describe the photometric monitoring procedures in Astro-WISE and give a first impression of OmegaCAM’s photometric behavior as a function of time. The long-term monitoring of the observatory goes hand in hand with the KiDS survey production in Astro-WISE. KiDS is observed under partially non-photometric conditions. Based on the first year of OmegaCAM operations it is expected that a ∼ 1–2 % photometric homogeneity will be achieved for KiDS.

Notes

Acknowledgments

The OmegaCAM consortium was formed in response to an announcement of opportunity from ESO, and comprises institutes in the Netherlands (NOVA, in particular the Kapteyn Institute Groningen and Leiden Observatory), Germany (in particular University Observatories of Munich, Gottingen and Bonn) and Italy (INAF, in particular Padua and Naples observatories). The ESO Optical Detector Team designed and built the detector system. OmegaCAM is headed by PI K. Kuijken (Leiden University). We acknowledge the good support by ESO staff during OmegaCAM commissioning, with special thanks to Steffen Mieske and Dietrich Baade. OmegaCAM is funded by grants from the Dutch Organization for Research in Astronomy (NOVA), the German Federal Ministry of Education, Science, Research and Technology (grants 05 AV9MG1/7, AV9WM2/5, 05 AV2MGA/6 and 05 AV2WM1/2), and the Italian Consorzio Nazionale per l’Astronomia e l’Astrofisica (CNAA) and Istituto Nazionale di Astrofisica (INAF), in addition to manpower and materials provided by the partner institutes. OmegaCAM dataflow operations in The Netherlands are supported by Target (www.rug.nl/target).
