Item _reflns_class.R_factor_gt


Description 

              For each reflection class, the residual factor for significantly
               intense reflections (see _reflns.threshold_expression) included
               in the refinement.
               The reflections also satisfy the resolution limits established by
               _reflns_class.d_res_high and _reflns_class.d_res_low.
               This is the conventional R factor. See also the
               definition of _reflns_class.wR_factor_all.

                   sum | F(obs) - F(calc) |
               R = ------------------------
                         sum | F(obs) |

               F(obs)  = the observed structure-factor amplitudes
               F(calc) = the calculated structure-factor amplitudes

               and the sum is taken over the reflections of this class.
