The uncorrected radius distributions for planets in single and binary star systems. The thin blue distribution is the radius distribution for planets in single-star systems from B. J. Fulton et al. (2017). The black distribution is the circumprimary radius distribution for planets in binaries from K. Sullivan et al. (2023). The red distribution is the K. Sullivan et al. (2023) circumprimary distribution modified to account for the more likely circumsecondary planets identified in this work. The change in the radius distribution for planets in binaries is minimal and tentatively confirms the absence of a radius gap reported in K. Sullivan et al. (2023).
