sources along the line of sight, where lenses and sources come from the same distribution from this point of view. The refinement of the detection probabilities including all important geometries is more likely to increase the overall probabilities of detection from current calculations than otherwise—perhaps sufficiently to motivate the creation of the necessary telescope array for a dedicated search. As about 3% of nearby stars have giant planets orbiting within 0.2 AU, possibly migrating there from further away, the most important contribution of an intensive microlensing search for planets may be the verification that many Jupiters are located where they are likely to have formed, thereby preserving the space closer to the stars for terrestrial planets.
