Numbers in parentheses correspond to the outermost resolution shell.
CC1/2 = Pearson’s correlation coefficient between average intensities of random half data sets for each unique reflection (Karplus and Diederichs, 2012).
Rmerge = ΣhklΣi|Ii(hkl) − <Ī(hkl)>|/ΣhklΣiIi(hkl), where Ii(hkl) and <Ī(hkl)> are the i and mean measurement of the intensity of reflection hkl.
Rwork = Σhkl||Fobs(hkl)| − |Fcalc(hkl)||/Σhkl|Fobs(hkl)|, where Fobs(hkl) and Fcalc(hkl) are the observed and calculated structure factors, respectively. No I/σ(I) cutoff was applied.
Rfree is the R value obtained for a test set of reflections consisting of a randomly selected ∼5% subset of the data set excluded from refinement.
