Refinement of F² against ALL reflections. The crystal was a nonmerohedral
twin by 180 deg. rotation about the reciprocal 0 0 1 axis. Refinement was
against HKLF 5 data, and the BASF parameter refined to 0.425(2).

 All esds (except the esd in the dihedral angle between two l.s. planes) 
 are estimated using the full covariance matrix.  The cell esds are taken 
 into account individually in the estimation of esds in distances, angles 
 and torsion angles; correlations between esds in cell parameters are only 
 used when they are defined by crystal symmetry.  An approximate (isotropic) 
 treatment of cell esds is used for estimating esds involving l.s. planes.
