R
merge =
.
R
cryst =
−
, 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.
