Macromolecular dictionary (mmCIF) version 2.0.09
For each reflection class, the weighted residual factors for all reflections included in the refinement. The reflections also satisfy the resolution limits established by _reflns_class.d_res_high and _reflns_class.d_res_low. See also _reflns_class.R_factor_ definitions. ( sum w [ Y(obs) - Y(calc) ]^2^ )^1/2^ wR = ( ------------------------------ ) ( sum w Y(obs)^2^ ) Y(obs) = the observed amplitude specified by _refine.ls_structure_factor_coef Y(calc) = the calculated amplitude specified by _refine.ls_structure_factor_coef w = the least-squares weight and the sum is taken over the reflections of this class.
