Ixion 2020–2023 Stellar Occultations — Final f–g Plane Geometry Used for the Global Shape Fit

This dataset contains the final f–g plane geometry derived from all stellar occultations of (28978) Ixion observed between 2020 and 2023. It provides the refined ingress and egress positions, event-centre offsets, timing uncertainties, shadow velocities, and chord lengths used in the global shape fit of Ixion. These coordinates represent the exact values adopted in the analysis and follow the SORA conventions (Gomes-Júnior et al., 2022), ensuring full reproducibility of the modelling results.
