_refine_special_details
;
Refinement on F^2^ for ALL reflections except for 3 with very negative 
F^2^
or flagged by the user for potential systematic errors.  Weighted R-
factors
wR and all goodnesses 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 observed 
criterion
of F^2^ > 2sigma(F^2^) is used only for calculating _R_factor_obs 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.
