Distributions of small planets of log R/R_⊕ < 0.8 (or R/R_⊕ < 6.3) and with periods shorter than 3.6 days, after categorizing their population into bins with a width of log P(day) = 0.125. Top panel: Distribution of planet radii against the orbital period. The distributions are shown as “boxenplots” or “letter value plots” (Hofmann et al. 2011). TOI-1416 b is indicated by the red star. Bottom panel: Counts of the small planets versus the same bins in orbital period.
