   Polarization ratio of the diffraction beam incident on the
   crystal. It is the ratio of the perpendicularly polarized to the
   parallel polarized components 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).

The permitted range is 0.0 -> infinity
