Description 


              Residual factor R for reflections that satisfy the resolution
               limits established by _refine_hist.d_res_high and
               _refine_hist.d_res_low and the observation criterion
               established by _reflns.observed_criterion.

               R = ---------------------
                        sum|F~obs~|

               F~obs~  = the observed structure factor amplitudes
               F~calc~ = the calculated structure factor amplitudes

               sum is taken over the specified reflections
