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.
