[14.17] UBVRIJHK Color-magnitude Diagram of Old Open Cluster NGC 6791

A. R. Hansen, G. Worthey (Washington State)

UBVRI photometry was obtained in two fields near open cluster NGC 6791 in April 1997 with the MDM Observatory 1.3m telescope. These data were reduced to the Johnson-Cousins system and combined with 2MASS JHK photometry to produce a multicolor color-magnitude diagram. Literature abundances and isochrones indicate that NGC 6791 is both old and about twice as metal-rich as the sun.
