The AllWISE science data products are distributed to the community via the online and computer-compatible services of the NASA/IPAC Infrared Science Archive (IRSA).

I.5.a. Online Access

I.5.a.i. Source Catalog and Other Databases

The IRSA/WISE archive contains the AllWISE Source Catalog and Reject Table extracted from the coadded Atlas Images, the Multiepoch Photometry Database, and metadata tables associated with the Atlas images and source tables. Logical queries on the AllWISE Catalog and Databases can be made via the IRSA/Gator online query engine. Gator enables searches on any Table attribute, such as position, brightness, color, quality flags, etc., or combinations thereof. Queries may be submitted using either a simple "Query-By-Table" form or with user-customizable SQL input. For example, one common query type is to search for all sources within a specified sky region, which can be most efficiently achieved using the query panel with spatial constraints.

Note: Gator is not designed to support very large downloads of the WISE/NEOWISE/AllWISE Catalogs or Databases. Specifically, if the return data volume exceeds 2Gb, Gator will truncate the query. So be cautious when your return table is close to 2Gb in size. See below for Catalog bulk download instructions.

I.5.a.ii. Images

The AllWISE Atlas Image products are accessed using the IRSA WISE Image Archive Service. This web-based interface enables selection, display and retrieval of full or subsections of the AllWISE Atlas Images and the Atlas and Single-exposure Images from the All-Sky, 3-Band Cryo and NEOWISE Post-Cryo releases, as well. Images can be queried by position or time (in the case of the Single-exposure images) of observation using the information stored in the image metadata. The returned images are in the native pixel format and projection of the image products. Both interactive and batch requests are supported by the image service.

The IRSA Image Mosaic Service builds custom mosaics of AllWISE and WISE Atlas Images (as well as other large-area image data sets such as 2MASS, DSS and SDSS) up to 2x2 deg. in size on user specified centers, projections and pixel scales.

The AllWISE Full-depth Ecliptic Polar Atlas Images can be retrieved via the links in section IV.5.

I.5.a.iii. Atlas Tile Look-up Service

Use the WISE All-Sky Release Tile Lookup Tool to determine in which Atlas Tile a specified location or object can be found.

I.5.b. Application Programming Interface

IRSA provides program-friendly interfaces to query and retrieve tabular and image data from the WISE mission. These URL-accessible services provide query and download functionality that can be accessed directly from a web browser, or by writing and running a simple "wget" or "curl" script on their local Unix system. Documentation on using these services is available on the IRSA site via the following links:

IRSA catalog query service (Gator) program interface documentation

IRSA image query service program interface documentation

I.5.c. Electronic Access to the Full Catalog and Databases

Bulk downloads of the AllWISE Source Catalog, Reject Table and Multiepoch Photometry Database in bzip2 compressed ASCII form are available at:

The Databases are divided into multiple compressed files, each file containing the source records within a distinct declination band. Wget scripts are available for each of the tables to download all of the Catalog or Database parts. When uncompressed, the tables are formatted in a simple bar-delimited manner consistent with convenient loading into a database server. The column order and contents of the AllWISE Catalog and Reject Table columns are as described in Section II.1.a, and the Multiepoch Photometry Database column order and content is described in Section III.1.a.

Be aware that the Catalog and Database Tables are extremely large, even in bzip2-compressed format. Please follow the links for each of the tables to determine how much storage space is required to download and unpack the tables.
