_reflns_class.R_Fsqd_factor

Definition:

   
     Residual factor R(F^2^) for reflections in this class judged
     significantly intense (i.e. greater than required by the
     _reflns.threshold_expression) and included in the refinement.
 
                      sum | F(meas_gt)^2^ - F(calc)^2^ |
        R(Fsqd gt) = ------------------------------------
                              sum F(meas_gt)^2^
 
      F(meas_gt)^2^ = square of the 'observed' structure-factor
      F(calc   )^2^ = square of the calculated structure-factor
 
           and the sum is taken over the specified reflections
