Data type: numb

Must appear in a looped list

Enumeration range: 0.0 -> infinity


   The value of Rmerge(I) for all reflections 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.
