Fig. 1 --- The red, green, and blue lines represent the amplitude that planetary transits produce in stellar light curves as a function of the planet's parent star's Main-Sequence spectral type (or size). The red, green, and blue lines represent planets with sizes of Jupiter, Neptune, and the Earth respectively. Yellow lines denote the precision level achievable by the various projects discussed in this poster. The photometric precision for both single (few minute) exposures and the precision achieved by time-averaging light curves into 5-hour bins are shown. Ground-based surveys for extra-solar planets are sensitive enough to detect terrestrial-sized planets transiting late-type dwarfs and can provide very high signal-to-noise light curves for transits of giant planets across stars with a wide variety of spectral types.
