- Description:
- 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 Single-exposure Source Working Database contains positions and brightness information, uncertainties, time of observation and assorted quality flags for 9,479,433,101 "sources" detected on the individual WISE 7.7s (W1 and W2) and 8.8s (W3 and W4) Single-exposure images. Because WISE scanned every point on the sky multiple times, the Single-exposure Database contains multiple, independent measurements of objects on the sky. Entries in the Single-exposure Source Table include detections of real astrophysical objects, as well as spurious detections of low SNR noise excursions, transient events such as hot pixels, charged particle strikes and satellite streaks, and image artifacts light from bright sources including the moon. Many of the unreliable detections are flagged in the Single-exposure Table, but they have not been filtered out as they were for the Source Catalog. Therefore, the Table must be used with caution. Users are strongly encouraged to read the Cautionary Notes before using the Table.

- Description:
- The AllWISE program extends the work of the successful Wide-field Infrared Survey Explorer mission (WISE; Wright et al. 2010, AJ, 140, 1868) by combining data from the cryogenic and post-cryogenic survey phases to form the most comprehensive view of the mid-infrared sky currently available. AllWISE has produced a new Source Catalog and Image Atlas with enhanced sensitivity and accuracy compared with earlier WISE data releases. Advanced data processing for AllWISE exploits the two complete sky coverages to measure source motions for each Catalog source, and to compile a massive database of light curves for those objects. WISE is a National Aeronautics and Space Administration (NASA) Medium Class Explorer mission that scanned the sky methodically in the 3.4, 4.6, 12 and 22 #m mid-infrared bandpasses (hereafter W1, W2, W3 and W4) in 2010 and 2011. The 40 cm WISE telescope and payload equipped with four 1024x1024 pixel focal plane detector arrays were cooled by a dual-stage solid hydrogen cryostat. WISE carried out its 4-Band (or Full) Cryogenic survey from 2010 January 7 to 2010 August 6, observing the sky 1.2 times with all four detectors operating at full sensitivity. After the hydrogen ice in the outer cryogen tank evaporated, WISE surveyed an additional 30% of the sky during its 3-Band Cryo phase, with the W1 and W2 detectors operating at near full sensitivity, and the W3 focal plane operating at reduced sensitivity. The NEOWISE Post-Cryo phase (Mainzer et al. 2011 ApJ, 731, 53), funded by the NASA Planetary Division, started on 2010 September 29 after cryogen in both tanks was exhausted, and continued until 2011 February 1. NEOWISE Post-Cryo observations covered 70% of the sky with W1 and W2 detectors operating at near full sensitivity. Images and extracted source data from each of the three survey phases were release separately in the March 2012 All-Sky Data Release, the June 2012 3-Band Cryo Data Release, and the May 2013 NEOWISE Post-Cryo Release.

- Description:
- The WISE 3-Band Cryo Data Release products are comprised of data taken during the mission's 3-Band Cryo survey phase. This phase covers the time following the exhaustion of solid hydrogen in the WISE payload outer cryogen tank, while the detectors and telescope were still cooled by the inner cryogen tank. During this time, WISE's W1, W2 and W3 bands were operational and continued to acquire useful data, but the W4 detector was saturated by thermal emission from the warming telescope. The sensitivity achieved in the W1 and W2 bands was similar to that during the full cryogenic mission phase. The W3 measurement sensitivity was degraded and decreased steadily during the 3-Band Cryo phase because of the increasing telescope temperature and decreasing exposure times. WISE scanned approximately 30% of the sky during the 3-Band Cryo survey phase continuing with the same strategy that was used during the full cryogenic survey. The following table contains brief descriptions of all metadata information that is relevant to the production of the Atlas images and Source Catalog. The table contains the (RA, DEC) of the center of the Tile. Much of the information in this table is processing-specific and may not be of interest to general users (e.g., flags indicating whether frames have been processed successfully or not, and the date and time of the start of the pipeline processing, etc.). The metadata table also contains some characterization and derived statistics of the coadd image Tile, basic photometric parameters used for photometry and derived statistics for extracted sources and artifacts. For example, it contains median pixel values of the coadded sky coverage map, the number of sources with profile-fit photometry Signal-to-Noise (SNR) greater than 3, and the total number of real sources affected by artifacts such as optical ghosts, etc.

- Description:
- NASA's Wide-field Infrared Survey Explorer (WISE; Wright et al. 2010) mapped the sky at 3.4, 4.6, 12, and 22 um (W1, W2, W3, W4) in 2010 with an angular resolution of 6.1", 6.4", 6.5", & 12.0" in the four bands. During the full cryogenic survey phase, 7 January 2010 to 6 August 2010, when the detectors and telescope were cooled by solid hydrogen in both inner and outer cryogen tanks, WISE achieved 5 sigma point source sensitivities better than 0.08, 0.11, 1 and 6 mJy in unconfused regions on the ecliptic in the four bands. The sky was covered 1.2 times during this period, and the data acquired were used to construct the products for the March 2012 WISE All-Sky Data Release. The WISE 3-Band Cryo survey phase began on 6 August 2010 following the exhaustion of frozen hydrogen in the payload's outer cryogen tank. WISE scanned approximately 30% of the sky over the next 54 days while the focal planes were cooled by hydrogen ice in the inner cryogen tank. The telescope warmed from the 12 K maintained during the main mission to 45 K. Imaging data in the 3.4, 4.6 and 12 um bands were acquired, but elevated thermal emission from the telescope prevented useful data from being collected in the 22 um band. As illustrated in Figures 1 and 2, the 3-Band Cryo 3.4 and 4.6 um band measurements are nearly as sensitive as those in the full cryogenic survey, but the increasing temperature and reduced exposure times of the 12 um measurements result in significantly lower sensitivity.

- Description:
- The WISE 3-Band Cryo Single Exposure (L1b) Source Table contains positions and photometry in the 3.4, 4.6 and 12 μm bands for 3,703,319,374 sources extracted from observations made during the WISE 3-Band Cryo survey phase, 6 August 2010 through 29 September 2010. WISE scanned approximately 30% of the sky during this period when the telescope and focal planes operated at a slightly higher temperature, but were still cooled by solid hydrogen in the inner cryogen tank. The Known Solar System Object Possible Associations List is a compendium of asteroids and comets, with orbits known at the time of WISE second-pass data processing, that were predicted to be within the field-of-view at the time of individual WISE exposures. Individual objects were observed multiple times, so may have multiple entries in the list. When the predicted position of a solar system object is in proximity to a detection in the WISE single-exposures, the WISE source position and brightness information are also provided.

The following table contains brief descriptions of all metadata information that is relevant to the processing of Single-exposure (level 1) images and the extraction of sources from the corresponding Single-exposure images. The table contains the unique scan ID for a specific scan frame and the reconstructed right ascension and declination of the level 1b frame center. Much of the information in this table is processing-specific, and may not be of interest to general users (e.g. flags indicating whether frames have been processed or not, and the date and time for starting of the pipeline, etc.). The metadata table also contains some characterization and derived statistics of the Single-expsoure image frames, basic photometric parameters used for photometry and derived statistics for extracted sources and artifacts. For example, it contains median pixel values of the coadded sky coverage map, the number of sources with profile-fit photometry Signal-to-Noise (SNR) greater than 3, and the total number of real sources affected by artifacts such as electronic ghosts, etc.

- Publisher:

- Description:
- The WISE 3-Band Cryo Source Working Database (WDB) contains positions and photometry in the 3.4, 4.6 and 12 μm bands for 261,418,479 sources extracted from observations made during the WISE 3-Band Cryo survey phase, 6 August 2010 through 29 September 2010. WISE scanned approximately 30% of the sky during this period when the telescope and focal planes operated at a slightly higher temperature, but were still cooled by solid hydrogen in the inner cryogen tank. CAUTION: The 3-Band Cryo Source WDB is not a well-vetted, reliable list of infrared sources like the WISE All-Sky Release Source Catalog. The WDB contains both detections of real astronomical objects, as well as spurious detections of image artifacts, noise excursions, transient events such as cosmic rays, satellite trails and hot pixels. The WDB also contains redundant extractions of objects that fall in the overlap region between the 3-Band Cryo Atlas Tiles. The WISE 3-Band Cryo Source WDB is best used as a resource to learn more about objects that are found in the All-Sky Release Source Catalog. The 3-Band Cryo observations offer a second, independent epoch of measurement for objects in 30% of the sky, so can be used to test for object motion, flux variability and reliability in the case of very faint sources. 3-Band Cryo WDB entries have been cross-correlated with the All-Sky Catalog and associated Catalog source information is provided in the 3-Band Cryo WDB records.
