_reflns_class.R_factor_gt

Definition:

   
     Residual factor for the 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) - F(calc) |
    R(F gt) = --------------------------------
                     sum | F(meas_gt) |
 
           F(meas) = the measured structure-factor amplitudes
           F(calc) = the calculated structure-factor amplitudes
 
           and the sum is taken over the specified reflections
