Boötes Field

The Boötes Field is a 9-square-degree survey field, one of two fields defined in the late 1990s, chosen as relatively free of infrared cirrus, for the NOAO Deep Wide-field Survey (NDWFS), a optical/NIR survey. The expression deep wide indicated the survey would provide what was normally thought of as a deep-field level of detail, but over a wider field, reflecting the technology improvements of the time. The field has been the target of subsequent surveys aiming to build a substantial set of observational data for a set of astronomical objects. These include surveys using Herschel Space Observatory, Spitzer Space Telescope, Chandra X-ray Observatory, Low-frequency Array, the Allen Telescope Array, and the Isaac Newton Telescope.
