The main web page now contains links to synthetic movies and predicted light curves of each of the events. The uncertainties here are quite large in time, depth, and duration of event. One of the difficulties is that the transits/occultations are occurring close to the limb of Haumea, so small changes in impact parameter make huge differences. The nice thing about this sensitivity is that a few good detections should strongly constrain the geometry.
While one should not yet take these models too seriously, they are a good indicator of the type of modeling that will be needed to interpret these observations.
