Description 


              Polarisation ratio of the diffraction beam incident on the
               crystal. It is the ratio of the perpendicularly polarised to the
               parallel polarised 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).
