Reanalysis of the 15 August 2018 event based on the IXON observational data from the online supplemental data file of Silva-Cabrera et al. (2022). The raw data were normalized, with the flux contribution of the Pluto system carefully removed by Silva-Cabrera et al. (2022). The uncertainties used for weighting are the standard deviation of the data outside the occultation part for each station. Panel (a): Reconstructed occultation map. Panel (b): Observed and simultaneously fitted light curves. Panel (c): Reconstructed stellar paths seen by IXON. Panel (d): The χ² map, where χ² denotes the goodness-of-fit value using these data. The best-fitting χ² value per degree of freedom is 1.046.
