Abstract:
We present the results of VRI photometry of the young open cluster IC
2602. Two 15x15arcmin2 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 (1994ApJS...90..467D 1994ApJS...90..467D),
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, ≥50%, 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. (1995A&A...300..134R 1995A&A...300..134R)
present complimentary narrow band Hα photometry for a subset of
the stars.
