  • a Values in parentheses represent the highest-resolution shell.

  • b Rmerge = Σ i Σ hkl | I (hkl) − < I (hkl) > | /Σ hkl Σi Ii (hkl), where Ii (hkl) is the observed intensity, and < I (hkl) > is the average intensity from multiple measurements.

  • c R factor = Σ(Fobs − Fcalc) / ΣFobs.

  • d Rfree is the R factor for a subset (5%) of reflections that were selected prior to the refinement calculations but not included in the refinement.
