Each of the observed particles may thus be first reoriented and standardized by putting its axis of symmetry in vertical position and by assigning the ordinate y = -1/2 to its lowest point and the ordinate y = 1/2 to its top in the planar case and proceeding analogously with the assignment of the z-values in the spatial case (should this operation admit different realisations we shall choose the one which leads to the largest value of the test statistic to be calculated).
