Mean figure of merit for multiple anomalous dispersion phasing (2.65 Å)				0.692

^*Friedel mates are treated as unique reflections for data reduction in multiple anomalous dispersion experiments.

^† R_merge = ∑|I − 〈I〉 |/∑I, where I is the observed intensity and 〈I〉 is the average intensity calculated for replicate data.

^‡ Mean figure of merit = ∑cos〈Δα_i〉/n, where Δα_i is the error in the phase angle for reflection i, and n is the number of reflections.
