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

We present new UBVRI photometry of the Hyades-aged open cluster NGC 6811 taken at the WIYN 0.9m. Spatially-dependent PSF photometry was performed using DAOPHOT, and aperture corrections were applied. Using multiple color-color and color-magnitude diagrams, we re-evaluate the cluster's reddening, metallicity, distance, and age. This project falls under the auspices of the WIYN Open Cluster Study, a collaboration between Indiana University, Yale University, the University of Wisconsin, and NOAO. This work is supported by the National Science Foundation under grant AST-0206202 to CPD.
