The correlation coefficient for the elliptical distortion for refinement under constraint of an orthorhombic crystal system. The horizonal axis represents the rotation of the crystal lattice vectors away from the orientation a || x. The phases of elliptical distortion 0° (blue) and 45° (orange) are shown and αmax was 60°.
