Item Description

The R factor for merging the reflections that satisfy the resolution limits established by _diffrn_reflns.d_resolution_high and _diffrn_reflns.d_resolution_low and the observation limit established by _diffrn_reflns.observed_criterion. Rmerge(I) = [sumi(sumj|Ij - |)] / [sumi(sumj)] Ij = the intensity of the jth observation of reflection i = the mean of the amplitudes of all observations of reflection i sumi is taken over all reflections sumj is taken over all observations of each reflection
