ESM and TSM metrics for TOI-1685 b. Top: ESM for exoplanets with a radius of less than 3 R_⊕. Bottom: TSM for exoplanets with a radius of less than 3 R_⊕ but larger than 1.5 R_⊕. All planets have mass determination by either RVs or TTVs. TOI-1685 b is labeled and marked with a thicker black borderline in both panels. For most exoplanets, the error bars, in distance, are smaller than the symbol size. The uncertainties in the ESM and TSM are only plotted for TOI-1685 b.
