SPT-Spitzer Deep Field
The first delivery (DR1) of the
"SPT-Spitzer Deep Field" (SSDF)
is available here using spatial and visualization tools.
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.
data are available
using IRSA's Catalog Search
which allows for complex search queries. Also available are SSDF image
" using IRSA's
which is a general tool to create single or multiple small FITS (and JPEG)
image cutouts of datasets archived at IRSA.
