Achieving 1% photometric accuracy with the ESO Wide Field Imager
Abstract
The highly successful Wide Field Imager on the ESO/MPG 2.2-m telescope offers the possibility of undertaking photometry over a half-degree field. The authors discuss findings concerning the photometric performance of the camera. They describe strategies for dealing with the flat-field calibration error, which is often underestimated by observers.
