Example Bioverse simulation of a survey to characterize Earth-sized planets in the HZ. This simulation used an 8 m diameter telescope observing at λ = 550 nm. This figure shows all rocky planets detected with R_p < 1.4R_⊕. Left panel shows the measured quantity of β = A_gR²Φ(α) as a function of instellation. Individual components of albedo, radius, and phase angle drawn from the Bioverse planet generation process including our injected trend are shown in the right subplots. This survey yields 44 exoEarth candidates, and the distribution of β shows a decrease at instellations corresponding to the HZ, reflecting the injected trend in albedo (see upper-right panel).
