_reflns_shell.Rmerge_F_obs

Name:
'_reflns_shell.Rmerge_F_obs'

Definition:

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

               sum~i~(sum~j~|F~j~ - <F>|)
   Rmerge(F) = --------------------------
                    sum~i~(sum~j~<F>)

   F~j~ = the amplitude of the jth observation of reflection i
   <F>  = the mean of the amplitudes of all observations of
          reflection i

   sum~i~ is taken over all reflections
   sum~j~ is taken over all observations of each reflection
