Open Cluster Database:

Introduction: The Open Cluster Database has been developed in order to provide easy reference to observational data and membership information for some of the nearer and better studied open clusters in the Galaxy. Clusters of particular interest are those for which candidate members in the solar-type and low-mass membership range have been identified through proper motion surveys, x-ray surveys, photometric/spectroscopic surveys or a combination of these methods. The data were compiled originally with the intent to provide an observational database to study the evolution of angular momentum among solar-type and low-mass stars as they evolve down to the zero-age main sequence, but undoubtedly may be applied towards other studies.
