Item Description
The standard uncertainty (estimated standard deviation, e.s.d.)
of _diffrn_radiation.polarizn_source_ratio,
(Ip-In)/(Ip+In), where Ip is the intensity
(amplitude squared) of the electric vector in the plane of
polarization and In is the intensity (amplitude squared)
of the electric vector in the plane of the normal to the
plane of polarization.
