There is described an X-ray system having at least one component that is shiftable or pivotable along at least one traverse path to at least one predeterminable locking position. The invention relates to the seeds of soybean cultivar S120104, to the plants of soybean cultivar S120104, to the plant parts of soybean cultivar S120104, and to methods for producing progeny of soybean cultivar S120104. The data is indicative of a system parameter that varies with time as a function of at least two variables related to system wash-in and wash-out behavior.
