Scientific paper

The Spitzer Science Center is in the process of generating a source list (SL) that will contain photometry for point sources in a large subset of imaging data in the Spitzer Heritage Archive (SHA). Fully reduced mosaic images and photometry for high significance objects in all four IRAC bands (3.6-4.5 micron) and the MIPS 24 micron band will be served by the SHA at the NASA Infrared Science Archive (IRSA) as an enhanced data product. These data will include Spitzer observations of about 1500 square degrees and 30 million sources, enabling a large range of exploratory projects and scientific results.
Validation of the source list began by comparing SL measurements to those made by the Legacy science projects. We have now begun an extensive exploration of SL data by undertaking several small, original science projects to independently verify the data products. In the poster we describe the current state of SL processing and discuss the range of use cases which will be supported. We show current results from the on-going validation science projects.
