Paper Abstract

Micro-arcsecond precision must rely on the detailed knowledge of instrument parameters and observing conditions for optimal definition of data reduction and calibration procedures. The variation of instrumental response over the field of view with wavelength and in time is potentially critical and often unavoidable. This work addresses selected topics in modeling of the astrometric instrument of the Gaia mission, evidencing their role in the data reduction strategy. Discussion is extended to how the modeling will impact on the data quality and to how the science data can be used to trace directly the instrument response. Finally mention is provided of the actual implementation of our recipe into the Astrometric Instrument Model, a software tool which will be used during the processing of Gaia data.
