Merging data in SHELXL

In this equation both summations involve all input reflections for which more than one symmetry equivalent are averaged. (F ) is the mean value of all measured equivalents. 

In this equation, the summation occurs over all reflections in the merged list, and CT (Fq ) is the estimated standard uncertainty of the merged reflection. In estimating the CT-value for a merged reflection, SHELXL uses the value obtained by combining
