SWIRE Data Deliveries
What is available?
SWIRE delivers images and source lists, for Spitzer+optical data.
Please note that when a Legacy team delivers enhanced data products to IRSA, the data must go through a quality assurance (QA) and ingestion process before being available through IRSA search engines, and this process does not happen instantaneously. Direct data access to a more recent delivery may contain errors that will be caught by the QA process; an IRSA search of an older delivery permits access to data that have passed the QA process.
For the data that have passed the QA process, IRSA offers a number of services connected to the SWIRE data, specifically:
The SWIRE team recommends that new users start with this summary web document, which contains considerable links to additional information.

Getting the original Spitzer data
All of the original Spitzer data for Legacy programs are released to the community as soon as they complete end-of-campaign reprocessing (there is no proprietary period). For general information about how to access our, archive (and what to do with the data when you get in), please see Data Archive and Data Analysis & Tools.
