Detailed Description

Polarization Correction.

So far, it only considers the correction for equatorial diffraction: $ P = \frac{1}{1+A}\left(1+A\cos^2(2\theta)\right) $ (Polarization factor), with $ A = \frac{1-f}{1+f} $, where f is the polarization rate of the incident beam in the plane which (i) includes the incident beam, and (ii) is perpendicular to the diffracting plane. For an X-Ray Tube without monochromator, A=1, and if there is a monochromator : $ A = \cos^2(2\theta_{mono}) $

Currently, the linear polarization factor is directly read from the radiation object, and the linear polarization (if any) is assumed to be perpendicular to the diffracting plane (standard synchrotron geometry).

Todo:
: extend this to take into account other diffracting & monochromatic geometries.
