The Astro2020 Decadal Survey recommended a" future large IR/O/UV telescope optimized for observing habitable exoplanets and general astrophysics" that would" search for biosignatures from a robust number of about~ 25 habitable zone [exo] planets," now dubbed the Habitable Worlds Observatory (HWO). The search for biosignatures requires high quality spectra of broad bandwidth and sufficient signal-to-noise. The combination of spectral resolution, bandwidth, and signal-to-noise-ratio impacts the number of exo-Earths that can be spectrally characterized. Previous work (Morgan et al. 2022), evaluated the number of Earth-size, habitable zone exoplanets that could be spectrally characterized for a range of spectral resolutions, signal-to-noise ratios, and bandwidths for a 6-m diameter exoplanet direct imaging mission. In this paper, we evaluate yield with two of those metrics for a range of parameters: aperture …
