From the web page:
NASA's Wide-field Infrared Survey Explorer (WISE; Wright et al. 2010)
mapped the sky at 3.4, 4.6, 12, and 22 μm (W1, W2, W3, W4) in 2010
with an angular resolution of 6.1", 6.4", 6.5", & 12.0" in the four
bands. WISE achieved 5σ point source sensitivities better than 0.08,
0.11, 1 and 6 mJy in unconfused regions on the ecliptic in the four
bands. Sensitivity improves toward the ecliptic poles due to denser
coverage and lower zodiacal background.
The All-Sky Release includes all data taken during the WISE full
cryogenic mission phase, 7 January 2010 to 6 August 2010, that were
processed with improved calibrations and reduction algorithms. Release
data products include an Atlas of 18,240 match-filtered, calibrated
and coadded image sets, a Source Catalog containing positional and
photometric information for over 563 million objects detected on the
WISE images, and an Explanatory Supplement that is a guide to the
format, content, characteristics and cautionary notes for the WISE All-
Sky Release products. The WISE All-Sky Data Release products supersede
those from the April 2011 Preliminary Data Release.
All-Sky Release ancillary products include a Reject Table containing
284 million detections that were not selected for inclusion in the
Source Catalog because they are low signal-to-noise ratio or spurious
detections of image artifacts, an archive of over 1.5 million Single-
exposure Image sets and a database of over 9.4 billion source
extractions from those images, and moving object tracklets identified
as part of the NEOWISE program (Mainzer et al. 2011).
