dc.description.abstractWe use Gaia DR2 magnitudes, colours and parallaxes for stars with G1.53 Msun and α2≈1.3 for the mass range between 0,5 and 1,53 Msun. This is the first time that we consider a non-parametric SFH for the thin disc in the Besancon Galaxy Model. This new step, together with the capabilities of the Gaia DR2 parallaxes to break degeneracies between different stellar populations, allow us to better constrain the SFH and the IMF.
