Values in parentheses are for the highest resolution shell.
Rmerge = ∑hkl∑i|Ii(h) - <I(h)>|/∑hkl∑i Ii(h), where I(h) is intensity of reflection h, <I(h)> is average value of intensity, the sum ∑hkl is over all measured reflections and the sum ∑i is over i measurements of a reflection.
Crystallographic R = ∑hkl||Fobs - Fcalc||/∑hkl|Fobs|, Rfree was calculated using a randomly chosen set of reflections that were excluded from the refinement.
