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