This project observed approzimately 1/3 of M31 in 6 photometric bands from the mid-UV through the near-IR. The PI was J. Dalcanton and my role started as an expert on the M31 Spitzer observations and evolved to leading the effort to fit the SEDs of the many millions of sources. See Dalcanton et al. (2012) for details of the survey. The data can be obtained from MAST.
