Geometric albedo of several hot and ultra-hot exoplanets as function of their estimated dayside temperature. The detection values (blue) or upper limits (green) are measured in the CHEOPS passband ($=A_g^{\text{CHEOPS}}$) and reported in the following works: Lendl et al. (2020), Hooton et al. (2022), Deline et al. (2022), Brandeker et al. (2022), Scandariato et al. (2022), Parviainen et al. (2022), Demory et al. (2023), Krenn et al. (2023), Pagano et al. (2024), Singh et al. (2024), Demangeon et al. (2024), Akinsanmi et al. (2024), and Scandariato et al. (2024). Measurements in the Kepler passband from Esteves et al. (2015) and Morris et al. (2024) are shown in grey.
