Item Description

The value of Rmerge(I) for reflections classified as 'observed' (see _reflns.observed_criterion) in a given shell. sumi(sumj|Ij - <I>|) Rmerge(I) = -------------------------- sumi(sumj<I>) Ij = the intensity of the jth observation of reflection i <I> = the mean of the intensities of all observations of reflection i sumi is taken over all reflections sumj is taken over all observations of each reflection

Additional Descriptive Information for Depositors

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

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

               I~j~ = the intensity of the jth observation of reflection 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
