Values in parentheses are for the highest-resolution shell.

R merge = ΣhΣj|I hj− 〈I h〉|/ΣhΣj|I hj|, where h represents a unique reflection and j represents symmetry-equivalent indices. I is the observed intensity and 〈I〉 is the mean value of I.

R work = Σ|F obsF calc|/ΣF obs, where F obs and F calc are the observed and calculated structure-factor amplitudes, respectively.

§

The R free value was calculated with a random 5% subset of all reflections excluded from the refinement.
