_refine_ls.wR_factor_gt

Definition:

   
     Weighted residual factors for significantly intense reflections
     (satisfying _reflns.threshold_expression) included in the refinement.
     The reflections must also satisfy the resolution limits established by
     _refine_ls.d_res_high and _refine_ls.d_res_low.
 
        ( sum w [ Y(meas_gt) - Y(calc) ]^2^  )^1/2^
   wR = ( ---------------------------------- )
        (         sum w Y(meas_gt)^2^        )
 
     Y(meas_gt) = the 'observed' amplitude _refine_ls.structure_factor_coef
     Y(calc)    = the calculated amplitude _refine_ls.structure_factor_coef
   w        = the least-squares weight
   and the sum is taken over the specified reflections
