Data collection statistics.

aNumbers in brackets refer to the statistical data for the outer resolution shell.bRmerge = ΣhΣi|Ii (h)−|/ΣhΣii (h)>, where Ii (h) is the intensity of an individual measurement of the reflection, and i (h)> is the mean intensity of the reflection.(a) 括号内的数值对应外分辨率壳层（outer resolution shell）的统计数据。(b) 合并R因子(Rmerge) = ΣₕΣᵢ|Iᵢ(h) − ⟨I(h)⟩| / ΣₕΣᵢIᵢ(h)，其中Iᵢ(h)为某一衍射反射的单次测量强度，⟨I(h)⟩为该衍射反射的平均强度。
