SITE UNDER CONSTRUCTION. PLEASE COME BACK SOON.

The WIYN One Degree Imager (ODI) is expected to produce image quality better by >~ 0.1" than any other existing or currently planned wide field imager. This improvement will be accomplished by the use of orthogonal transfer technology. The goal of the Yale/WIYN ODI survey is to take advantage of this new facility by carrying out a survey that will:

• Provide the basis for a variety of scientific projects for PIs at Yale and elsewhere
• Take advantage of the excellent image quality that is our primary competitive advantage over other wide-field imagers
• Exploit both time domain studies of individual images and deeper summed images
• Leverage the data acquired by other surveys in all wavelengths
• Provide a starting point for queue-based observing that other programs using ODI can tap into, if desired.

It is important to note that the Yale "survey" may in fact consist of a number of different projects carried out together. Thus we are imagining a "core" survey of fields all observed the same way; "extensions" to the survey pushing the limits in one or more of area, depth, filters, cadence in ways that benefit specific science goals; and "add-ons" which are projects not directly related to the survey proper, but which would benefit operationally if the data were obtained together with the survey data.

90 nights of time are already committed by Yale to this project (30/yr for the first three years of ODI operations) and we expect to apply to the Yale TAC for 60 additional nights (also in the first 3 years) following the completion of Yale's proposed purchase of nights from NOAO. Additional time may also be obtained from proposals to other partners (including NOAO) for extensions and additions to the survey. Modes of participation include all of the following:

• Participation in an existing science group (see Scientific Goals page for more information).
• Creation of a new science group to use the basic survey data.
• Proposals to extend the survey to enable or enhance particular science goals.
• "Add-on" science programs that would obtain and analyze data not part of the survey, but that could be executed as part of the survey queue ("bad seeing" proposals would be particularly welcome, but all projects adding nights to the queue would be welcome).
• Participation in the technical aspects of the project (e.g. scheduling, observing, data analysis, archiving). Obviously some professional expertise will be required in all these areas, and we expect there will be considerable scope for student participation as well.
