WIYN Open Cluster Study
The open cluster NGC 2420 (center) in the constellation Gemini along with the WIYN 0.9m (left) and 3.5m (right) telescopes located atop Kitt Peak near Tucson, Arizona (WIYN/NOAO/NSF).
A number of astronomers have formed a collaboration to establish a standard database of open cluster photometry, astrometry, and spectroscopy. The current members of this collaboration were at one time, or are currently, affiliated with one of the institutions responsible for the scientific mission of the WIYN telescope; these include the University of Wisconsin, Indiana University, Yale University, and the National Optical Astronomy Observatories. The coordinated effort of these researchers is known as the WIYN Open Cluster Study (WOCS, pronounced 'wox').
The project is supported by the National Science Foundation grants AST-0196212 and AST-0606703 (to the University of Florida), AST-9731302 (to the University of Wisconsin), AST-9812735, AST-0206202, and AST-0607567 (to Indiana University), and NASA grant NAG5-8406 (to Yale).
