R merge = Inline graphic Inline graphic.

R cryst = Inline graphicInline graphic Inline graphic, where F calc and F obs are the calculated and observed structure-factor amplitudes, respectively.

§

R free is the same as R cryst but for 5% of the total reflections chosen at random and omitted from refinement.

This value represents the total B that includes TLS and residual B components.
