[46.03] The HST Local Group Stellar Populations Archive

J. A. Holtzman, C. Afonso (NMSU), A. Dolphin (NOAO)

We describe an archive of stellar photometry measurements that we are constructing from a large fraction of all HST observations of Local Group galaxies. We present the techniques used to derive this database and show examples of the data products, which are available via the WWW. We describe some of the scientific analyses that we are pursuing using this database, including differential studies of luminosity and mass functions, locations of oldest main sequence turnoffs in different objects, and comparisons and derivations of star formation histories.
