Rmerge = ΣI − 〈I〉/ΣI, where I is the intensity of an individual measurement and 〈I〉 is the average intensity from multiple observations.
R-factor = ΣFobs − Fcalc/Fobs, where Fobs and Fcalc are the observed and the calculated structure-factor amplitudes, respectively.
R-free is the R-factor for a 5% subset of reflections not used in refinement.
