| Completeness (%) | 99.0 (97.2) | 99.9 (100) | 86.7 (49.3) |
〈I〉 is the mean intensity for all reflections and 〈σ(I)〉 is the mean sigma for these reflections.
R
merge =
, where Ii is the intensity of an individual measurement of a reflection and 〈I〉 is the mean value for all equivalent measurements of this reflection.
