Discussion:
The DAMIT model above is plotted at the expected diameter of Flora. With only one chord, it is not possible to tell if Dave was north or south of the centre line of the event. The miss suggests that he was north, but is too far removed to be positive. The model has been plotted centred on the observed chord.
The figure below shows the Tangra light curve of the occultation.
