Discussion:

The ellipse above is plotted at the maximum axis ratio as determined by lightcurve inversion data. this happily agrees fairly well with the plotted 3D shape With only one chord and a constraining miss we we can assert that John was north of the central line of the event and that the event was south of the predicted path. However we cannot be sure by how much. Given the similar slopes of the two edges there is quite a large range of possible solutions The DAMIT 3D model has been overlaid on the measured ellipse and shows reasonable fit to the ellipse from light curve data.

The figure below shows the Tangra light curve of the occultation.
