NASA's Wide-field Infrared Survey Explorer (WISE) mapped the
sky at 3.4, 4.6, 12 and 22 micrometers in 2010 with an
angular resolution of 6.1", 6.4", 6.5" and 12.0" in the four bands.
WISE achieved a 5 sigma point source sensitivities better and 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 zodaical background.

The WISE All-WISE
includes all data taking during the WISE full cryogenic phase, from January 7, 2010 to August 6, 2010, that were processed
with improved calibrations and reduction algorithms and combines this with the NEOWISE postcryogenic
survey to form the most comprehensive view of the full mid-infrared sky.

SkyView includes the four WISE bands as separate surveys. Many non-image
data products are available at the WISE site. Note that WISE data is
distributed in relatively large (>50 MB) image files. When SkyView generates
an image for a part of the sky where it has not yet cached the
data from the IPAC server there may be a delay as full tiles are downloaded
even when only a small fraction of a tile is needed. Images
in cached regions, are generated much faster. Access to
the WISE data uses the VO SIA interface maintained at IPAC. Even when
data is cached, the SIA service must still be available for successful
queries. Provenance: WISE Archive (IRSA/IPAC). This is a service of NASA HEASARC.
