Histogram of the absolute total O–C (distance on the sky) between the predicted and observed positions derived from stellar occultations. The bottom panel presents the O–C values normalised by the uncertainty of the occultation astrometry for each event. The curve labelled “2014–2020” includes only occultations around those years, while “best orbit” considers only orbits with σ_α < 1.6 × 10⁻¹⁰ au.
