Space group	I222
Unit cell, Å	122.5 by 222.5 by 374.2
Wavelength, Å	0.965
Mosaicity, °	0.44
Resolution, Å	20–2.8 (2.9–2.8)
Completeness, %	99.8 (99.4)
Redundancy	3.9 (2.9)

Rsym, %	6.7 (21.6)

Values in parentheses correspond to the highest-resolution shell. R_sym = Σ_i,h|I(i,h) − 〈I(h)〉|/Σ_i,h|I(i,h)|, where 〈I(h)〉 is the mean of the I observations of reflection h. R_sym was calculated with anomalous pairs merged; no sigma cut-off was applied.
