Discussion:

While Dave and John's observed chords are quite close together, it is quite clear that the actual centreline of the event was to their south. The fit is improved if the outline of (445) Edna is assumed to be slightly elliptical as shown above.

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