Spitzer-SPT Deep Field (SSDF) Overview
SSDF Overview SSDF Primary Data Access SSDF Cutouts SSDF Catalogs


The Spitzer-South Pole Telescope Deep Field (SSDF) is a wide-area survey using IRAC to cover 94 square degrees of extragalactic sky, making it the largest IRAC survey completed to date outside the Milky Way midplane. The SSDF is centered at 23:30,-55:00, in a region that combines observations spanning a broad wavelength range from numerous facilities. These include millimeter imaging from the South Pole Telescope, far-infrared observations from Herschel/SPIRE, X-ray observations from the XMM-XXL survey, near-infrared observations from the VISTA Hemisphere Survey, and radio-wavelength imaging from the Australia Telescope Compact Array, in a panchromatic project designed to address major outstanding questions surrounding galaxy clusters and the baryon budget.
