# 8. REFINEMENT DATA

_refine_special_details          
;
 Refinement on F² for ALL reflections except those
 flagged by the user for potential systematic errors.
 Weighted R-factors wR and all goodnesses of fit S
 are based on F², conventional R-factors R are based
 on F, with F set to zero for negative F². The
 observed criterion of F² > 2sigma(F²) is used only
 for calculating -R-factor-obs 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.
