Discussion:
The ellipse above is plotted at the best fit axis ratio as determined by Occult. With 2 chords we can be confident of the path of Tercidina and that it was south of the predicted line. The Damit 3D model has been overlaid on the measured ellipse and shows reasonable fit. Another chord further south might have improved that.
The figure below shows the Tangra light curve of John's occultations.
