Item Description

The standard uncertainty (estimated standard deviation, e.s.d.) of _diffrn_scan_frame.polarizn_Stokes_U, (Ip-In)*sin(2*theta), where Ip is the intensity (amplitude squared) of the electric vector in the plane of polarization, In is the intensity (amplitude squared) of the electric vector in the plane of the normal to the plane of polarization, and theta is the angle as viewed from the specimen, between the normal to the polarization plane and the laboratory Y-axis as defined in the AXIS category.
