Top panel: histograms of planet radii from the literature (black) and our revised values (orange), using 0.33 R_⊕ bin width. Dashed curves represent kernel density estimates (KDEs) computed with 0.33 R_⊕ bandwidth. Lower panel: KDE distributions of radius uncertainties, with vertical dashed lines indicating the medians: 0.05 (this work) and 0.10 (literature values from the NASA Exoplanet Archive).
