_refine.correlation_coeff_Fo_to_Fc

Name:
'_refine.correlation_coeff_Fo_to_Fc'

Definition:

   The correlation coefficient between the observed and
   calculated structure factors for reflections included in
   the refinement.

   The correlation coefficient is scale-independent and gives
   an idea of the quality of the refined model.

                sum~i~(Fo~i~ Fc~i~ - <Fo><Fc>)
  R~corr~ = ------------------------------------------------------------
            SQRT{sum~i~(Fo~i~)^2^-<Fo>^2^} SQRT{sum~i~(Fc~i~)^2^-<Fc>^2^}

   Fo = observed structure factors
   Fc = calculated structure factors
   <>   denotes average value

   summation is over reflections included in the refinement
