R
merge =
, where Ii(hkl) is the intensity of the ith measurement of reflection hkl and I(hkl) is the average value over multiple measurements.
R
cryst =
for all reflections (no cutoff), where F
obs and F
calc are the observed and calculated structure factors, respectively.
R free was calculated against 5% of the reflections removed at random.
