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.
