Updated parameters of 1743 open clusters based on Gaia DR2
  In this study we follow up our recent paper (Monteiro et al. 2020) and
present a homogeneous sample of fundamental parameters of open clusters in our
Galaxy, entirely based on Gaia DR2 data. We used published membership
probability of the stars derived from Gaia DR2 data and applied our isochrone
fitting code, updated as in Monteiro et al. (2020), to GB and GR Gaia DR2 data
for member stars. In doing this we take into account the nominal errors in the
data and derive distance, age, and extinction of each cluster. This work
therefore provides parameters for 1743 open clusters and, as a byproduct, a
list of likely not physical or dubious open clusters is provided as well for
future investigations. Furthermore, it was possible to estimate the mean radial
velocity of 831 clusters (198 of which are new and unpublished so far) using
stellar radial velocities from Gaia DR2 catalog. By comparing the open cluster
distances obtained from isochrone fitting with those obtained from a maximum
likelihood estimate of individual member parallaxes, we found a systematic
offset of $(-0.05\pm0.04)$mas.
