Abstract:
Large-scale astrometric and photometric data bases have been used to
search for and confirm stellar membership of the open cluster IC 2391.
125 stars were found that satisfied criteria for membership based on
proper motion components and BRI photometry from the United States
Naval Observatory B (USNO-B, Cat. I/284) catalogue and JHK
photometry from the Two Micron All Sky Survey (2MASS, Cat. II/246)
catalogue. This listing was compared with others recently published.
A distance to the cluster of 147.7±5.5pc was found with mean proper
motion components, from the Tycho2 catalogue of (-25.04±1.53mas/yr;
+23.19±1.23mas/yr). A revised Trumpler classification of II3r is
suggested. Luminosity and mass functions for the candidate stars were
constructed and compared with those of field stars and other clusters.
