§

If any reflections are measured more than four times then one cannot extract from HKL-2000 output the total number of measured reflections in a shell but merely a lower limit, hence the use of the ≥ sign.

R merge = Inline graphic Inline graphic, where I i(hkl) is the ith observation of reflection hkl and 〈I(hkl)〉 is the weighted average intensity for all observations i of reflection hkl.
