Summary of data collection, phasing and refinement statistics.

aValues in parentheses are for the highest resolution shell. b is the multiplicity (N) independent R. cMean correlation factor between two random subsets of anomalous intensity differences. In parenthesis, resolution at which anomalous correlation drops below 35%. dValue in parenthesis: resolution for which phasing power drops below 1.0. eIn parenthesis, number of reflections randomly assigned to the test set. f. R is defined as R for the test set. gThe value in parentheses corresponds to the test set reflections. hRoot mean square deviation from the standard values. iAs reported by the Molprobity server [57]. In parenthesis, the percentile of this value among structures of comparable resolution.
