AllWISE
A full-sky view with infrared wavelengths rendered in visible light, highlighting hot, dust-obscured galaxies
Description
(Taken from AllWISE Explanatory Supplement: Introduction) 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 μm 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.

The allwise.source table has been crossmatched with all other datasets in Data Lab within a 1.5 arcsec radius, nearest neighbor only. These tables will appear with x1p5 in their name in our table browser. Example: allwise.x1p5__source__decaps_dr2__object
Data Access
The AllWISE data are accessible by a variety of means:
Data Lab Table Access Protocol (TAP) service
TAP provides a convenient access layer to the AllWISE catalog database. TAP-aware clients (such as TOPCAT) can point to https://datalab.noirlab.edu/tap, select the allwise database, and see the database tables and descriptions. You can also view the AllWISE tables and descriptions in the Data Lab table browser.
Data Lab Query Client
The Query Client is available as part of the Data Lab software distribution. The Query Client provides a Python API to Data Lab database services. These services include anonymous and authenticated access through synchronous or asynchronous queries of the catalog made directly to the database. Additional Data Lab services for registered users include personal database storage and storage through the Data Lab VOSpace.
The Query Client can be called from a Jupyter Notebook on the Data Lab Notebook server. Example notebooks are provided to users upon creation of their user account (register here), and are also available to browse on GitHub at https://github.com/astro-datalab/notebooks-latest.
Jupyter Notebook Server
The Data Lab Jupyter Notebook server (authenticated service) contains an example of how to access and visualize the AllWISE catalog:
