Abstract
We have imaged an 11.5 deg2 region of sky toward the South Ecliptic Pole (R.A. =04h43m, decl. =-53°40', J2000) at 24 and 70 μm with MIPS, the Multiband Imaging Photometer for Spitzer. This region is coincident with a field mapped at longer wavelengths by AKARI and BLAST. We discuss our data reduction and source extraction procedures. The median 1σ depths of the maps are 47 μJy beam-1 at 24 μm and 4.3 mJy beam-1 at 70 μm. At 24 μm, we identify 93,098 point sources with signal-to-noise ratio (S/N) >=5 and an additional 63 resolved galaxies; at 70 μm we identify 891 point sources with S/N >=6. From simulations, we determine a false detection rate of 1.8% (1.1%) for the 24 μm (70 μm) catalog. The 24 and 70 μm point-source catalogs are 80% complete at 230 μJy and 11 mJy, respectively. These mosaic images and source catalogs will be available to the public through the NASA/IPAC Infrared Science Archive.
