Membership of the open cluster IC 4665.
Abstract
Probabfflties of membership, based on relative proper motions, for 275 stars in the field of IC 4665 are given. The cluster proper motion dispersion (m.e.) of 0.0009 yields 19 probable members ill the limited field studied (approx. 40' x 50'). The main sequence is believed to terminate at My + 3.5, or F6V. Key words: open clusters - relative proper motions - cluster membership probabilities
