Abstract
The Gaia-ESO Survey (GES) observed many open clusters as part of its
programme to spectroscopically characterise the various Milky Way populations.
GES spectroscopy and Gaia astrometry from its second data release are used here
to assign membership probabilities to targets towards 32 open clusters with
ages from 1-3800 Myr, based on maximum likelihood modelling of the 3D
kinematics of the cluster and field populations. From a parent catalogue of
14398 individual targets, 5033 stars with uniformly determined 3D velocities,
