Discussion:

The circle above is plotted at the expected 160 km diameter of Alexandra. With only one chord it is not possible to determine whether Bill was north or south of the central line of the event. Nor can we be sure of the scale of the DAMIT 3D image

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