Abstract We propose to create a catalog of stellar properties for all of the roughly 100 million stars in the Roman Galactic Bulge Time Domain Survey (GBTDS) fields with F146 mag less than 22 by combining Roman data with available photometry from Rubin, Euclid, Gaia, and Hubble to produce the most detailed catalog of stars in the GBTDS. This catalog will be essential to validate and characterize any exoplanet candidate signal detected in the GBTDS. For each target, we will provide estimates of the stellar radius, mass, effective temperature, luminosity, metallicity, age, surface gravity, proper motion, distance, extinction prior, and a binarity indicator flag. The success of the Roman mission to conduct demographic studies of exoplanets depends on a reliable and complete base stellar catalog.
