We present the results of VRI photometry of the young open cluster
IC 2602. Two fields were observed in
February and May 1991 using the 1-m Swope telescope at Las Campanas. Using
theoretical isochrones obtained from D'Antona & Mazzitelli
(1994), and allowing for observational and other
uncertainties, we identify 78 primary candidate members with 12<V<18.5
from their positions on colour-magnitude diagrams. We compare
the cluster field with an offset field of similar galactic latitude and
estimate the contamination due to background stars to be large,
, as might be expected given its low galactic latitude. We
also compare our photometry with that given for the X-ray detected
stars of Randich et al. (1995). We present complimentary
narrow band
photometry for a subset of the stars.
