  1. R.m.s., root mean square.
  2. Values in parentheses are for the highest resolution shell. Rmerge=ΣhΣi|Ih,i−Ih|/ΣhΣiIh,i, where Ih is the mean intensity of the i observations of symmetry related reflections of h. R=Σ|Fobs−Fcalc|/ΣFobs, where Fcalc is the calculated protein structure factor from the atomic model (Rfree was calculated with 5% of the reflections selected).
