ULLYSES Target Tables by Region

The tables below contain targets for ULLYSES observations, broken down by region. This page will be updated with additional tables as targets continue to be selected. The full target list will contain roughly 200 objects in ten star-forming regions in the Milky Way and in nearby low metallicity dwarf galaxies.
