Discussion:

The ellipses above are plotted at the maximum axis ratio (1.09) as determined by lightcurve inversion data. With 2 effective chords we can be confident of the path of Emita and that it was north of the predicted line.

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

The light curve shows an ABBA double star signature. The stars are calculated to have Magnitudes of 10.97 and 11.64 with a PA - 67.6 degrees ans separation of 312 milli arcseconds.
A paper will be submitted to JDSO.
