The central Galactic bulge sky region. We show the HST bulge survey footprint, where blue FoVs are ACS/WFC and purple FoVs are WFC3/UVIS. Underlaid is 2MASS (M. F. Skrutskie et al. 2006). Black outlines show the Roman GBTDS observing fields. The HST footprint covers approximately 1.1 deg2 (see Table 1).
