_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
