_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).
