Values in parentheses are for highest-resolution shell.
R meas = ∑hkl [N/(N−1)]1/2 ∑i |I(hkl)−<I(hkl)> |/∑hkl ∑I I(hkl), where N is the multiplicity of a given reflection.
R cryst = ∑||F obs| − |F calc||/∑|F obs| for all reflections.
R free was calculated on the 5% of data excluded from refinement.
