  1. Values in parentheses represent the highest resolution shell
  2. aRsym(I) = Σ hkl Σ i |I i (hkl) - I(hkl)|/Σ hkl Σ i I i (hkl) where the summations are over i observations of each reflections and all hkl. I(hkl) is the average intensity of the i observations. Rwork = |F(obs)-F(calc)|/F(obs)
  3. bNumber of selenium sites located by SOLVE
  4. cFigure of merit calculated from SOLVE
  5. dFigure of merit calculated from RESOLVE
  6. eRfree is calculated for 5% of randomly selected reflections not used in the refinement
