Refinement of F^2^ against ALL reflections.  The weighted R-factor wR and 
goodness of fit S are based on F^2^, conventional R-factors R are based 
on F, with F set to zero for negative F^2^. The threshold expression of 
F^2^ > 2sigma(F^2^) is used only for calculating R-factors(gt) etc. and is 
not relevant to the choice of reflections for refinement.  R-factors based 
on F^2^ are statistically about twice as large as those based on F, and R- 
factors based on ALL data will be even larger.

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.
