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 > 2sigma(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 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.

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 > 2sigma(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 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.
