The population of open clusters of the Galactic disc
We summarize the results of our recent study of the Galactic disc population of open clusters. This study makes use of a sample of 650 open clusters drawn from the analysis of the high-precision all-sky compiled catalogue ASCC-2.5. On the basis of the combined spatial–proper motion–photometric membership we established uniform scales of spatial (angular dimensions), kinematic (proper motions and radial velocities) and evolutionary (ages) cluster parameters. The sample is complete within 850 pc, which provides unbiased parameters of the local cluster population and its evolution.
