Item Description

Residual factor Rmerge for reflections that satisfy the resolution limits established by _reflns_shell.d_res_high and _reflns_shell.d_res_low and the observation criterion established by _reflns.observed_criterion. sumi(sumj|Fj - <F>|) Rmerge(F) = -------------------------- sumi(sumj<F>) Fj = the amplitude of the jth observation of reflection i <F> = 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
