The Spitzer Deep, Wide-Field Survey (SDWFS)
IRSA is currently serving the first data release (DR1.1) of the Spitzer Deep, Wide-Field Survey (SDWFS), a Cycle 4 Spitzer Legacy program. This project is a four-epoch survey of roughly 10 square degrees of the NOAO Deep, Wide-Field Survey field in Boötes. The first visit to the field occurred very early in the Spitzer mission, in 2004 January, as part of the IRAC Shallow Survey (Eisenhardt et al. 2004). Subsequent visits to the field as part of the SDWFS program reimaged the same area to the same depth (see delivery documentation).
DR1 consists of four-band IRAC mosaics, coverage maps, and catalogs corresponding to each of the SDWFS epochs. In total, there are 16 single-epoch mosaics and coverage maps, plus an additional set of four corresponding to the sum of all IRAC integrations of this field. DR2 added a variability catalog and light curves.
You can get a close-up map of a region by clicking on the above image, or by typing a coordinate below.
Use the form below to enter a coordinate or object name to search for data, or click the image above to retrieve cutout images for your area of interest (along with links to the original mosaics). SDWFS catalog data are available using IRSA's Catalog Search engine, which allows for complex search queries. You can also bypass searching and browse the images or catalogs.
The canonical paper for the SDWFS survey is Ashby et al. (2009). The canonical paper for the variability catalog and light curves is Kozlowski et al. (2010).
