Overview
These are version 1 high-level science products from GO-17776, "A Precursor Survey of the Roman Galactic Bulge Time Domain Fields". The early-release catalog includes 8 fields in the Galactic bulge (HD16-ACS, HD16-WFC3UV, HD70-ACS, HD70-WFC3UV, HD98-ACS, HD98-WFC3UV, HD138-ACS, and HD138-WFC3UV), where the team provides ACS and WFC3 photometry, astrometry, as well as photometry for cross-identified sources in GO-17173 (Nataf et al.) and Gaia DR3. The astrometry is given in distortion-free pixel coordinates and equatorial coordinates (degrees, J2000). Drizzled images for this program can be accessed via MAST as part of Hubble Advanced Products (HAP). The early-release catalog is assigned the DOI: 10.17909/fq12-f295.
An overview of the program can be found in Terry et al. 2026, ApJL, 1003, L1. More details can be found in the provided README.
