Estimated uncertainty of LPC original semimajor axis vs. LPC discovery year for dynamically new (﹩\tfrac{1}{{a}_{\mathrm{orig}}}\lt 1{0}^{-4}﹩ au⁻¹) LPCs listed in the CODE catalog (M. Królikowska & P. A. Dybczyński 2020). The shaded rectangle marks the time range and uncertainty range containing the observed dynamically new LPCs that we consider in most of our paper’s analyses. The dotted line marks all dynamically new LPCs discovered since 1990 with original semimajor-axis uncertainties below 2 × 10⁻⁶ au⁻¹.
