Separate fits done to PLANET data alone gave a similar result and so an electronic caustic alert was issued by PLANET..The last two points in red were taken after the model was generated.

Advantages to choosing small eclipsing binaries for such searches. These include the obvious advantage that eclipsing binary systems are already known to have their orbital planes very nearly edge-on to the observer& ,s line-of-sight, with subsequent planet formation expected to take place near the same plane. An additional damping of planetary orbits into the binary plane due to precession could also add to their coplanarity (Schneider 1994, Schneider and Doyle 1995)..For detection of

Months. At a temperate latitude site the Sun keeps us from seeing 1 2 to 2 3 of all transits, since it is daylight much of the time. At the the South Pole we can detect periodic transits up to 3 times faster than the California-based Vulcan project. The South Pole offers a unique land location where the stars never rise or set, minimizing the brightness change as we observe them through different amounts of atmosphere. The cold stable atmosphere also minimizes the changes in brightness that
