180∠551 (or2): the mean orientation of a population generated by BVND in the first (or second) time. The column vectors of a fracture parameter in two populations will be same if they are generated through the same mean in the same time (e.g., the orientation column vector of data 2 equals to the orientation column vector of data 4). 3.52-R4: the trace length column vector of data 2-R4 is rearranged from the trace length column vector of data 2. 32-R5: the aperture column vector of data 2-R5 is rearranged from the aperture column vector of data 2.
