a

Rmerge for replicate reflections, R = Σ|Ih − <Ih>|/Σ<Ih>; Ih is intensity measured for reflection h; <Ih> is average intensity for reflection h calculated from replicate data.

b

Crystallographic R factor, Rwork = Σ||Fo| − |Fc||/Σ|Fo| for reflections contained in the working set. Free R factor, Rfree = Σ||Fo| − |Fc||/Σ|Fo| for reflections contained in the test set held aside during refinement. |Fo| and |Fc| are the observed and calculated structure factor amplitudes, respectively.
