Item Description

Residual factor for the reflections (with number given by _reflns.number_gt) judged significantly intense (i.e. satisfying the threshold specified by _reflns.threshold_expression) and included in the refinement. The reflections also satisfy the resolution limits established by _refine.ls_d_res_high and _refine.ls_d_res_low. This is the conventional R factor. See also _refine.ls_wR_factor_ definitions. 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 specified reflections
