This logic is commonly used before determining the euler angles of class sums. Its purpose is to perform a sensitive mass centering of the class sums based on radon transformation. Usage of this algorithm improves common line finding during the consecutive reconstruction process. | This logic is commonly used before determining the euler angles of class sums.
