Core dictionary (coreCIF) version 2.4.5
For each reflection class, the weighted residual factors for all reflections included in the refinement. The reflections also satisfy the resolution limits established by _refine_ls_class_d_res_high and _refine_ls_class_d_res_low. ( sum w [ Y(obs) - Y(calc) ]^2^ )^1/2^ wR = ( ------------------------------ ) ( sum w Y(obs)^2^ ) Y(obs) = the observed amplitudes specified by _refine_ls_structure_factor_coef Y(calc) = the calculated amplitudes specified by _refine_ls_structure_factor_coef w = the least-squares weights and the sum is taken over the reflections of this class. See also _refine_ls_class_R_factor_ definitions.
