[14.22] WIYN Open Cluster Study: UBVRI CCD Photometry of the Hyades-aged Open Cluster NGC 6811

E. M. Mills, C. P. Deliyannis (Indiana University), I. Platais (Johns Hopkins University)

We present precision photometry of the Hyades-aged open cluster NGC 6811. Observations were made in the U, B, V, R, and I filters with the WIYN 0.9m on Kitt Peak. PSF photometry was performed using DAOPHOT, and aperature corrections were applied. We present revised values for the reddening, metallicity, distance, and age of the cluster. This project falls under the auspices of the WIYN Open Cluster Study (WOCS), a collaboration between Indiana University, Yale University, the University of Wisconsin, and the National Optical Astronomical Observatories (NOAO). This work is supported by the National Science Foundation under grant AST-0206202.
