_reflns_shell.Rmerge_I_obs

Name:
'_reflns_shell.Rmerge_I_obs'

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
