One paper in Acta. Cryst. (2006) D62, 1369-1374 described the same
problem of pseudo-symmetry. To lower the Rfactor they used (h+k+l=2n+1)
odd reflections for rigid body refinement and (h+k+l=2n) even
reflections for restrained refinement. By this way they could decrease
R/Rfree from (0.425/0.434) to (0.235/0.311).
