Updating the DAML02 catalog using Gaia data

Reliable fundamental parameters of open clusters such as distance, age and extinction are key to our understanding of the Galactic structure and stellar evolution. In this work we present astrometric and fundamental parameters for thousands open clusters investigated using Gaia data, based on memberships determined using a combination of methods applied to Gaia astrometric data as well as obtained from other authors in the literature. Mean radial velocities were also determined for 47% of the clusters, many of which had no previous published values. The distances and ages determined through our improved isochrone fitting, now takes into account the interstellar extinction using an updated extinction polynomial for the Gaia photometric band-passes. A Galactic abundance gradient has also been used as a prior for metallicity along with an extinction prior based on the 3D structure of the Local Galaxy. The updated procedure was validated with a sample of clusters with high quality [Fe/H] determinations. Based on this catalog we present a critical review of the literature showing that our cluster parameter determinations represent a substantial improvement in fundamental parameter estimates. This has allowed us, for example, to re-estimate the rotation velocity of the arms of the Galaxy (28.5 +/- 1.0 km/s/kpc) from the clusters birthplaces, implying that the corotation radius is close to the solar Galactic orbit (R_c/R_0 = 1.01 +/- 0.08)
