System and method for improving immersion scanner overlay performance are described. The base bottom portion of the molded member is made so that a center slit having substantially an H-shape, a pair of slide slits, and slit-less bridge portion. Also provided by the invention are tissue cultures of the soybean variety A1016497 and the plants regenerated therefrom. The articles then drop following the shape of a parabola toward the center area of a dispersal table, with momentum gained from sliding down the bottom surface of the first gate. A precipitate agent is preferable added to the liquid in the third tank to remove heavy metals and the precipitate is periodically backwashed from the filter into the first tank. The selected bits may then be modulated by a modulator using quadrature phase shift keying.
