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.
