WHIRC: WHIRC is a near infrared high resolution imaging camera, commissioned in 2008 for the 3.5m telescope. WHIRC was a joint project between the WIYN partners and STSci. It consists in a 2k x 2k detector providing an excellent pixel scale of 0.1"/pixel and a field of view of 200 x 200 arcsec. WHIRC can be used with the WIYN Tip/Tilt Module (WTTM) to provide exquisite high-resolution images. A large set of filters is available.
ODI: The One Degree Imager (ODI) is the flagship of WIYN's new instrument initiatives. ODI will utilize both WIYN's one degree field of view and excellent image quality. The focal plane of the optical imager will be sampled with 0.1" pixels, or 1 Gigapixels in total. The sharpness of images will be actively improved by correcting images for tip/tilt image motion during the integration corrections will be done over the entire field of view, using a novel detector technology called Orthogonal Transfer Array CCD, making ODI a unique and competitive instrument in the era of wide-field surveys. ODI is funded by the WIYN partners and the National Science Foundation. It is expected that scientific programs will be undertaken with ODI starting in the second semester of 2010.

Governance

The WIYN Consortium is governed by the Board of Directors, which includes three members of each partner institution. The Board meets twice a year. The Science Advisory Committee provides scientific guidance to the Board and the WIYN Director.

Between 2000-2008, the WIYN Director was Dr. George Jacoby, followed by Dr. Pierre Martin (2008-2010). Since December 2010, Dr. Pat Knezek serves as interim director.
