Description

This component has no physical size (like Arm - also drawn that
way), but is used to set the polarisation in one of four ways:
1) (randomOn=0, normalize=0) Hardcode the polarisation to the vector (px, py, pz)
2) (randomOn!=0, normalize!=0) Set the polarisation to a random vector on the unit sphere
3) (randomOn!=0, normalize=0) Set the polarisation to a radnom vector within the unit sphere
4) (randomOn=0, normalize!=0) Hardcode the polarisation to point in the direction of (px,py,pz) but with polarization=1.
Example: Set_pol(px=0, py=-1, pz=0)

Input parameters

Parameters in boldface are required; the others are optional.

Name	Unit	Description	Default
px	1	X-component of polarisation vector (can be negative)	0
py	1	Y-component of polarisation vector (can be negative)	0
pz	1	Z-component of polarisation vector (can be negative)	0
randomOn	1	Generate random values if randomOn!=0.	0
normalize	1	Normalize the polarization vector to unity length.	0
