All SWIRE Spitzer image data is now released.
This data release adds the final remaining fields (ES1 and CDFS) to Data Release 2, and additionally adds the data formerly embargoed by the GTO program in the Lockman Hole. Otherwise it is supplemental to DR2. No changes were made to the EN1, EN2 and XMM data. As of now, all Spitzer data from SWIRE is available.
SWIRE imaging products consist of several parts:
The images are available from IRSA with a graphical and searchable interface. We also highly recommend using the IRSA image cutout service, which will allow you to upload coordinate tables and receive small image cutouts at every wavelength for each target.
The following table contains shortcuts to the IRSA image server. You should probably use the ATLAS links, since these are the least likely to break due to aging of the web structure.
Notes: XMM-LSS is part of the CFHT-Legacy Survey, and optical imaging data is available from them. Optical data for ELAIS-S1 is not currently available.
There are seperate catalogs for each SWIRE field, and four primary catalog types at this time.
Additional Ancillary Data
The primary document is the data release paper for DR2, which will soon be updated to include the last two fields of DR3.
There are also data release notes for DR2/3. These notes contain late-breaking information not included in the explanatory supplement, and are required reading.
Future Data Releases
It is unlikely (as of 2017) that any more data products will be formerly released. If you want to work with SWRE data and suspect we may have a data product you want but have not released, please contact us.
Note: The SWIRE Data Release 1 (Fall 2004) is now deprecated. Users should use Data Release 2/3, which includes a rerelease of all version 1 data. The Data Release 1 notes are found on the following web pages and contained important information, in particular in regards to known systematic errors in this catalog release.
