Fraction (upper), occurrence rate (middle), and mean host-star metallicity of synthetic planets with masses or radii similar to Earth in the temperate zone (Kopparapu et al. 2014). The error-bars depict the standard error of the mean. The cuts based on radii are the same as in Dressing & Charbonneau (2015) and Bryson et al. (2021). The resulting f⊕ and η⊕ sensitively depend on this choice.
