Reanalysis of the FTN data obtained during the November 29, 2011 stellar occultation by Chiron; (Ruprecht et al. 2015; Sickafoose et al. 2020). Adopting the preferred pole position proposed on Ortiz et al. (2015), we fit the light curves with two sharp-edged semitransparent rings, accounting for the stellar velocity perpendicular to the ring as measured in the ring plane. Data are shown in black, the ring models are plotted in blue, and the red curves are the synthetic light curves, accounting for diffraction, stellar diameter, and finite integration time. The green crosses at the bottom are the fit residuals to the synthetic light curve. The times were corrected by –7 s with respect to the values published in Ruprecht et al. (2015) and Sickafoose et al. (2020), so they are back to their original values (see text).
