Abstract
The Visible and Infrared Survey Telescope for Astronomy (VISTA) will be
mostly dedicated to the execution of ESO public surveys, requiring large
amounts of service observing time. VISTA Science Verification (SV) thus
differs from that usually implemented for other VLT instruments. VISTA
SV consisted of two self-contained mini-surveys: a Galactic mini-survey
in the region around the Orion Belt stars; and a deep extragalactic
mini-survey of the nearby spiral galaxy NGC 253. ESO astronomers used
these mini-surveys as benchmarks to optimise the survey operation
procedures, minimise overheads, and experience the full end-to-end
process of survey data acquisition. The raw data and associated
calibrations from both mini-surveys were released in December 2009, and
the reduced images and catalogues will soon be available, enabling the
first exciting science with VISTA.
