TLQS twinning

TLQS (Twin Lattice Quasi-Symmetry) twinning is a term employed to indicate twinning where the twin lattice is close to a higher holohedry. The degree of quasi-symmetry is commonly measure by the twin obliquity, which depends on the perpendicularity of lattice row / lattice plane [uvw]] / (hkl) defining the cell of the twin lattice.
