a

Values in the parentheses are statistics of the highest resolution shell.

b

Rmerge=Ij<I>Ij, where Ij is the intensity of an individual reflection and < I > is the average intensity of that reflection.

c

Rwork=FoFcFo, where Fc is the calculated structure factor. Rfree is as for Rwork but calculated for a randomly selected 5.0% of reflections not included in the refinement.
