STELLAR GALACTIC POPULATION CHARACTERIZATION USING GAIA PHOTOMETRY

摘要

The spectroscopic features to be measured, their dependence as a function of T_(eff), log g or [M/H] for the various types of stars leading us to the design of the medium pass-bands, central wavelength and their blue and red limits are described. The design particularly accounts for the scientific key targets for the study of the origin and history of our Galaxy. This paper focusses on the Geneva-Barcelona medium-band photometric system.
