Name:
'_pdbx_refine_tls.S[2][2]'

Definition:

   The [2][2] element of the screw-rotation tensor S. This should
   be given in the same coordinate frame as the
   corresponding anisotropic displacement parameters.

   The trace of S is indeterminate by crystallography, and should
   be set to zero.
