R merge = Inline graphic Inline graphic, where Ii(hkl) and 〈I(hkl)〉 represent the diffraction-intensity values of the individual measurements and the corresponding mean values. The summation is over all unique measurements.

R meas is a redundancy-independent version of R merge: R meas = Inline graphic Inline graphic Inline graphic.
