_diffrn_radiation.polarisn_ratio

Name:
'_diffrn_radiation.polarisn_ratio'

Definition:

   Polarization ratio of the diffraction beam incident on the
   crystal. This is the ratio of the perpendicularly polarized
   to the parallel-polarized component of the radiation. The
   perpendicular component forms an angle of
   _diffrn_radiation.polarisn_norm to the normal to the
   diffraction plane of the sample (i.e. the plane containing
   the incident and reflected beams).
