Numbers in parentheses refer to the highest-resolution shell.

Rmerge = (ΣhΣi|Ii(h) − 〈I(h)〉|/ΣhΣiIi(h))× 100, where 〈I(h)〉 is the average intensity of i symmetry-related observations of reflections with Bragg index h.

Rwork = hkl|FoFc|/Σhkl|Fo) × 100, where Fo and Fc are the observed and the calculated structure factors, respectively, for 95% of the reflections used in the refinement. Rfree was calculated as for Rwork but on 5% of reflections excluded before refinement. Numbers refer to Fo > 4σ data.
