**Definition:**

Residual factor Rmerge for all reflections that satisfy the resolution limits established by _reflns_shell.d_res_high and _reflns_shell.d_res_low. sum~i~(sum~j~|F~j~ - <F>|) Rmerge(F) = -------------------------- sum~i~(sum~j~<F>) F~j~ = the amplitude of the jth observation of reflection i <F> = the mean of the amplitudes of all observations of reflection i sum~i~ is taken over all reflections sum~j~ is taken over all observations of each reflection
