We have compiled a new catalogue of open clusters in the Galaxy
which updates the previous catalogues of Lyngå (1987) and of
Mermilliod (1995) (included in the WEBDA database). New objects
and new data, in particular, data on kinematics (proper motions,
radial velocities) that were not present in the old catalogues, have
been included. Virtually all the clusters (1622) presently known
were included, which represents an increment of about 450 objects
relative to the Lyngå (1987) catalogue. The catalogue is
presented in a single table containing all the important data
(positions, reddenings,
distances, ages, kinematics) which makes it easy to use. The catalogue includes mean absolute proper motions for hundreds of
open clusters (Dias et al. 2001, 2002a) obtained using the Tycho2
proper motions. Unpublished mean radial velocities of several
dozens of clusters are
also presented in this work. The catalogue is being constantly updated and the latest version can
be accessed on-line at
http://www.astro.iag.usp.br/~wilton/ were more data such
as membership probabilities for individual stars can also be
accessed.
