Title: Ground-based observations for Gaia`s calibrations: Creating initial test fields at the ecliptic poles
Abstract:
The astrometric satellite mission Gaia will revolutionise our
understanding of the Galaxy, the immediate solar neighbourhood, and many
aspects of stellar physics. The accuracy of the parallaxes and proper
motions derived by Gaia will be an improvement of several orders of
magnitude over currently available data, complemented by radial
velocities, abundances, and photometry. In order to test and verify the
complete Gaia system, all relevant components need to be tested and
calibrated soon after launch. For this we have chosen the fields around
the two ecliptic poles, which can be observed by Gaia at any given time.
This proposal applies to complete the multi-colour-wide-field imaging
required to create calibration fields around the southern ecliptic pole.
