The Spitzer Science Center (SSC) and Infrared Science Archive (IRSA) have released a set of Enhanced Imaging Products from the Spitzer Heritage Archive. These include enhanced mosaic images created from multiple AORs where appropriate and a source list (SL) of photometry for compact sources. The enhanced imaging products include data from the four channels of IRAC (3-8 microns) and the 24 micron channel of MIPS. The Source List was designed to prioritize reliability over completeness. In order to make the Source List reliable, many sources were rejected. Therefore, it is not complete at any flux density. At bright flux densities, nearby galaxies may be rejected for being too extended, or for being too close to a neighboring galaxy. At faint flux densities, sources will be missing because they do not meet the signal-to-noise cut. Although the Source List is useful for many science projects, users who require high levels of completeness are encouraged to use caution. If you are interested in a source that does not appear in the Source List, you should first inspect the Coverage Table to ensure that the data exists, and then consider measuring the photometry on the Super Mosaics yourself.
