These are datasets for the community to use to test the different reduction tecnhiqiues with the goal of comparing techniques allowing us to arrive at a set of "best practices" for high precision photometry with IRAC. We expect to add more test datasets in the future.
This dataset was used for the Data Challenge associated with the 2014 summer AAS workshop. It includes both simulated data and a dataset from the archive.
The datasets used for the second Data Challenge, at the 2015 IAU Workshop also include both simulated and real data.
