Discussion:

The Ellipse above is plotted at the the same area as the expected 72 km diameter of Iphigenia. Lightcurve studies have implied a maximum ellipse axis ratio of 1.32. With only two close chords there is an ambiguity in the solution but the one shown is the better fit. With two chords we can be confident of the path of Iphigenia and that it was north of the predicted line.
