Discussion:

The DAMIT model above is plotted at the expected diameter of Aspasia. With only one chord, it is not possible to tell if Brian was north or south of the centre line of the event. The model has been plotted centred on the observed chord.

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