_reflns_class.R_I_factor

Definition:

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