Preparing the modelling of Gaia products for Galactic structure and dynamics with mock datasets
Résumé
A series of workshops { the 'Gaia Challenge' { has been initiated in 2013 to prepare the scienti c exploitation of Gaia data. The rst position and velocity observables from Gaia will be released early in 2017. Within this context, I present results from numerical tools developed to constrain Galactic structural and dynamical properties from pseudo Gaia observables (mock data).
