Actually the experiment can be thought of as trying to map the gravity well using a whole pattern of stars. Eddington mapped 14 stars in 1919. And the current project recently executed in Mexico might be able to compare several hundred thousand stars against the superb stellar positional atlases that have been made by satellite surveys and contain well over a billion stars.
One should be able to get a pretty cool diagram of the geometric distortion of space using all this data. You could probably do some kind of flip back and forth between the distorted positions of these thousands of stars and their regular mapped positions with no solar gravity well.
The Washington Post link below is a free link. It provides enough information to get a pretty good idea of the methodology.
