The PHAT survey is collecting photometric data with 3 cameras aboard the Hubble Space Telescope covering about one quarter of the M31 inner disk and bulge. The observing strategy allows coverage of the full survey area in 6 broad bands from the Near-UV to the Near-IR. Initial survey photometry has been performed on the data from each camera separately, then the resulting catalogs have been matched to improve astrometry and provide our first 6-band catalogs. We provide a summary of our crowding-optimized point spread function measuring technique. We present color-magnitude diagrams showing our data quality in each camera for areas of varying surface brightness in M31, and we present color-color diagrams to show the quality of our current ability to match stars across all 6 bands. These data are samples of the survey's first public data release to the Hubble data archive. Finally we present preliminary results from simultaneous photometry across all 6 bands where matching is done at the pixel level, eliminating the need for catalog matching. This new ability provides optimal depth in overlapping fields and more reliable matching of all 6 bands. Future survey data releases will include such optimized 6-band photometry. PHAT is supported by HST GO-12055 administered by NASA.
