SWIRE Image Atlas -- DR3 -- 20051121

Summary

The following completes the data release of all Spitzer data from all
observations from the SWIRE program. Three of the six SWIRE fields are
included in this data release:

1) New images for the Lockman Hole, which include data formerly  embargoed
in the previous data release (DR2). As of this release, all of the  data are
contiguous. Users should now use these images instead of those  previously
released. New optical images are also included.

2) Spitzer IRAC and MIPS images for the Chandra Deep Field South (CDFS)
and ELAIS South (ELAIS-S1) regions. These data are new and have not been
released before.

For the other three fields (ELAIS-N1, ELAIS-N2, and XMM-LSS) users  should
continue to use the images from Data Release 2. Catalog data products  are
also available for the three fields given above. In addition to the
standard IRAC-MIPS24 (and optical, for Lockman) bandmerged catalogs, we
additionally include separate source lists for the three MIPS detectors,
which do not have the IRAC-detection criterion found in the bandmerged
catalog.
