The WISE Archive is an implementation of the Source Catalogues of the
preliminary and the all-sky data releases of the
WISE (Wide-field Infrared Survey Explorer) mapped the sky at 3.4, 4.6, 12, and
22 μm 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 WISE Preliminary Release includes data from the first 105 days of WISE survey observations, 14 January 2010 to 29 April 2010, that were processed with initial calibrations and reduction algorithms. The Source Catalogue contains positional and photometric information for over 257 million objects detected on the WISE images.
The WISE All-Sky Release Source Catalogue contains positions and four-band photometry for 563,921,584 objects detected in 18,240 Atlas Tiles.
Each Catalogue entry gives positions, magnitudes, astrometric and photometric uncertainties, flags indicating the reliability and quality of the source characterizations, and associations with any nearby 2MASS Point and Extended Source Catalogue.
