R
merge =
, where 〈I(hkl)〉 is the mean intensity of symmetry-equivalent reflections.
R
work =
, where F
obs and F
calc are the observed and calculated structure-factor amplitudes, respectively.
The R free value was calculated as for the R factor but using only a test set of reflections (5% of the total) that were not used in the refinement.
