Abstract:
CCD photometry on the intermediate-band vbyCaHβ system is
presented for the metal-rich, old open cluster NGC 6791.
Description:
New photometric data for NGC 6791 were obtained using the 0.9 meter
Wisconsin-Indiana-Yale-NOAO (WIYN) telescope on Kitt Peak, on five
photometric nights between 2004 May 27 and May 31.
