^† R _merge = , where I _i(hkl) is the intensity of reflection hkl and is the sum over all i measurements of reflection hkl.

^‡The R factor R _work = , where F _obs and F _calc are the observed and calculated structure factors, respectively.

^§ R _free is the R factor calculated over a subset of the data that were excluded from refinement.
