Stellar Clusters in M31 from PHAT: Survey Overview and First Results
  The Panchromatic Hubble Andromeda Treasury (PHAT) is an on-going Hubble Space
Telescope (HST) multi-cycle program that will image one-third of the M31 disk
at high resolution, with wavelength coverage from the ultraviolet through the
near-infrared. This dataset will allow for the construction of the most
complete catalog of stellar clusters obtained for a spiral galaxy. Here, we
provide an overview of the PHAT survey, a progress report on the status of
observations and analysis, and preliminary results from the PHAT cluster
program. Although only ~20% of the survey is complete, the superior resolution
of HST has allowed us to identify hundreds of new intermediate and low mass
clusters. As a result, the size of the cluster sample within the Year 1 survey
footprint has grown by a factor of three relative to previous catalogs.
