   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.

        ( sum w [ Y(obs) - Y(calc) ]^2^  )^1/2^
   wR = ( ------------------------------ )
        (         sum w Y(obs)^2^       )

   Y(obs)  = the observed amplitudes specified by
   Y(calc) = the calculated amplitudes specified by
   w       = the least-squares weights

   and the sum is taken over the reflections of this class. See
   also _reflns_class_R_factor_ definitions.
