Discussion:

The circle above is plotted at the expected 115 km diameter of Xanthippe. With only one chord it is not possible to determine whether Steve was north or south of the central line of the event. The circle fits very well when drawn touching the end points and the centre is very close to predicted pathe but without a second chord or constraining misses we cannot be sure so it is shown on the observed chord.

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