Scientific paper

The table presents tidal radii and masses of 650 Galactic open clusters. The tidal radii are derived from a relation between a semi-major axis A of the density distributions of cluster members and fitted King radii (J/A+A/468/151). The cluster masses are found from cluster tidal radii assuming that the latter are good approximations of limiting radii for local clusters moving at nearly circular orbits. The clusters are a sample of the Catalogue of Open Cluster Data and their members are selected from the high-precision, homogeneous all-sky catalogue ASCC-2.5 (Kharchenko, 2001, Cat. ). The clusters in the table are sorted according to their order in the COCD.
