This definition has been superseded and is retained here only for archival purposes. Use instead '_reflns_shell_Rmerge_F_gt'


   The value of Rmerge(F) for reflections classified as 'observed'
   (see _reflns_observed_criterion) in a given shell.

               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.
