^† R _merge = , where I_i(hkl) and 〈I(hkl)〉 are the observed intensity of measurement i and the mean intensity of the reflection with indices hkl, respectively.

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

^§ R _free is the R factor for a subset of 5% of the reflections that were omitted from refinement.
