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