The Wide-field Infrared Survey Explorer (WISE;
Wright et al. 2010)
and the Infrared Processing and Analysis Center (IPAC)
announce the WISE All-Sky Data Release.
WISE surveyed the entire sky at 3.4, 4.6, 12 and 22 microns in 2010,
achieving 5-sigma point source sensitivities better than 0.08, 0.11, 1
and 6 mJy in the four bands in unconfused regions on the ecliptic
plane. The WISE All-Sky Release incorporates all data taken during
the WISE full cryogenic mission phase, 7 January to 6 August 2010.
All data were reprocessed with improved calibrations and reduction
algorithms for the All-Sky Release. Release data products include an
Atlas of match-filtered, calibrated and coadded images in the four
WISE bands, a Source Catalog containing positions and four-band
photometry for over 563 million objects, and an Explanatory
Supplement.
Ancillary products include an archive of calibrated WISE
single-exposure images and a database of 9.4 billion source
extractions made from those images, and moving object tracklets
identified by the NEOWISE program (Mainzer et al. 2011).
A quick guide to the Release data products, data access instructions
and supporting documentation
is available. A summary of the WISE mission resources is available on the WISE mission page.
