This definition has been superseded and is retained here only for archival purposes.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

Definition:

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

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

   I~j~  = the intensity of the jth observation of reflection i
   <I> = the mean of the intensities of all observations of
          reflection i

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