Membership in the open cluster NGC 6494.
Abstract
An image position finding procedure for PDS microdensitometer measures of astrometric plates is described and applied to the open cluster NGC 6494. Probabilities of membership based on relative proper motions for 304 stars in the cluster field yield a cluster proper motion dispersion (m.e.) of 0.0005 and 169 probable members.
