Resolution limits at ≈50% completeness in the last-resolution shell (≈dmin + 0.1 Å). All difference maps calculated to 1.9-Å resolution.

W, wiggler; U, undulator.

Calculated from single reflections only.

Calculated from all reflections including harmonics

Rmerge(|F|) = Σ ||F| - 〈|F|〉|/Σ |F| where 〈|F|〉 is the mean amplitude of multiple observations and symmetry measurements. Rmerge(F2) = Σ ||F|2 - 〈|F|2〉|/Σ |F|2 where 〈|F|2〉 is the mean intensity of multiple observations and symmetry measurements.
