Beam finder workflow algorithm for SANS instruments. This algorithm is rarely called directly. It is called by SANSReduction or HFIRSANSReduction.
This algorithm abstracts out the details of how to call the FindCenterOfMassPosition algorithm. By using the ReductionProperties property, the algorithm will store previously calculated results so that the center doesn’t have to be recalculated every time we load a new file.
