a Rpim = Σhkl √(1/N − 1)Σi|Ii(hkl) − ¯Ii(hkl)|/Σhkl ΣiIi(hkl) with i running over the number of independent observations of reflection hkl.

b Rcryst = ΣhklFo(hkl)| − |Fc(hkl)‖/Σhkl|Fo(hkl)|.

c Rfree = ΣhklTFo(hkl) − |Fc(hkl)‖/ΣhklT|Fo(hkl)| where T is a test data set randomly selected from the observed reflections prior to refinement. The test data set was not used throughout refinement and contained 7.5% of the total unique reflections.
