Values in parentheses indicate the specific values in the highest resolution shell.
aRmerge = 
, where 
is the intensity of the measured reflection, and 
is the mean intensity of all the symmetry-related reflections.
bRwork = 
, where 
denotes the observed structure factor amplitude and 
denotes the structure factor amplitude calculated from the model. Rfree is as for Rwork but calculated with 5.0% of randomly chosen reflections omitted from the refinement.
