Index Group Members Objectives RVS characteristics Work breakdown Bibliography and data Workshops and meetings Links	Definition phase (2001 - 2002): Optimize the RVS design ... optical and mecanical design focal plane assembly (number of CCDs, pixel size, ...) spectral resolution ... with respect to RVS/GAIA science goals crowding in dense area on-board computation and data-handling telemetry budget Assess radial velocity accuracy versus magnitude, source type and spectral dispersion. Assess accuracy of derived stellar atmospheric parameters versus magnitude, source type and spectral resolution. Quantify the telemetry budget and devise strategies to optimize it. Compute/observe reference spectra Consolidation phase (2003 - 2004): Optimize the RVS detailed design Quantify the telemetry budget and devise strategies to optimize it (pre-processing tasks). Define, implement and test calibration strategy in the context of GDAAS (global iterative solution) Define global strategy to analyse the spectroscopic data in the context of GDAAS Develop RVS data simulator(s) Assess the RVS RV detailed accuracy budget Assess accuracy of derived stellar and interstellar parameters versus magnitude, source type Develop methods to interpret RVS/GAIA information in the context of the galactic and stellar structure Compute/observe reference spectra
