Discussion:
The circle above is plotted at the expected 83 km diameter of Pomona. With only one chord it is not possible to determine whether Chris was north or south of the central line of the event. The ISAM 3D model has been overlaid on the measured ellipse and shows reasonable fit to a circle
The figure below shows the Tangra light curve of the occultation.
