Dc. Foster et al., CCD PHOTOMETRY OF LATE-TYPE STARS IN THE YOUNG OPEN CLUSTER IC-2602, Astronomy & Astrophysics. Supplement series, 126(1), 1997, pp. 81-90
We present the results of VRI photometry of the young open cluster IC
2602. Two 15 arcmin x 15 arcmin fields were observed in February and M
ay 1991 using the 1-m Swope telescope at Las Campanas. Using theoretic
al isochrones obtained from D'Antona & Mazzitelli (1994), and allowing
for observational and other uncertainties, we identify 78 primary can
didate members with 12 < V < 18.5 from their positions on colour-magni
tude diagrams. We compare the cluster field with an offset field of si
milar galactic latitude and estimate the contamination due to backgrou
nd stars to be large, greater than or equal to 50%, as might be expect
ed given its low galactic latitude. We also compare our photometry wit
h that given for the X-ray detected stars of Randich et al. (1995). We
present complimentary narrow band H alpha photometry for a subset of
the stars.
