7. Conclusions

We have presented VRI and narrow band tex2html_wrap_inline1201 photometry of two tex2html_wrap_inline1665 fields near the centre of the young open cluster IC 2602. The VRI photometry was used to prepare colour-magnitude diagrams. Through the use of theoretical isochrones, we have identified 78 primary candidate cluster members. Using similar techniques on a nearby offset field, and through comparison with data on the Pleiades cluster from the literature, we have estimated the level of background contamination to be tex2html_wrap_inline1669%. The tex2html_wrap_inline1201 data was also used to prepare colour-magnitude diagrams. The location of the photometrically selected stars on these diagrams reinforces the likelihood of their being cluster members. Independent methods, such as a proper motion study, or a study of radial velocities, are needed to confirm the selected stars as cluster members.
