Abstract:
UBVRI Hα CCD photometry has been obtained fro the young cluster
NGC 2264. Using (R-Hα) color, a measure of Hα emission, we
selected member stars in the pre-main sequence (PMS) stage.
Description:
UBVRI Hα CCD photometry was performed on two nights during the
1997 Feb 28 and March 4 observing run at Siding Spring Observatory
with the 40" telescope (f/8) and a thinned Site 2048x2048 CCD.
