 Refinement of F² against ALL reflections. The weighted
 R-factor wR and goodness of fit S are based on
 F², conventional R-factors R are based on F,
 with F set to zero for negative F². The threshold expression
 of F² > σ(F²) is used only for calculating
 R-factors(gt) etc. and is not relevant to the choice of
 reflections for refinement. R-factors based on F² are
 statistically about twice as large as those based on F, and
 R-factors based on ALL data will be even larger.

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