Gaia PS	Tasks
Tasks Texts Presentations Members Links Photos	To refine the GAIA case for extrasolar planets (differentiate among different planetary formation models; planetary frequency with age; systems which can support life) To evaluate the impact of photometric and astrometric noise intrinsic to the sources To provide corresponding inputs to accuracy requirements and payload design To provide inputs to the simulation task To define optimal methods for the detection of candidate systems To evaluate the combination of GAIA photometry, spectroscopy, and preliminary parallax data to optimize the candidate list To assess the need for detectability requirements at the level of core processing To establish methods for orbital fiting (including strategies for finding initial values of orbital parameters) To perform extensive simulations of detection and orbit determination (including double-blind tests) To develop a reduction model for the parallel processing (algorithms, inputs, outputs) To establish needs and capabilities for ground-based follow-up observations
