Discussion:

The ellipse above is plotted at a reasonable fit to the ISAM model shape. With 2 chords we can be confident of the path of Elektra and that it was south of the predicted line.
The ISAM 3D model has been overlaid on the measured ellipse and shows reasonable fit.

The figure below shows the Tangra light curve of John's occultation at home.
