Hello all
In radio astronomy the orientation angle of an ellipse is usually quoted as
tan(2 *Psi) = S2/S1
Where S2 and S1 are the stokes parameters.
Does anyone know or can point me to a reference as to why the 2 * psi should be in there? The angle of the axis in the ellipse should be able to go between -Pi/2 to Pi/2? Does it have something to do with the fact that you can rotate all your polarisers by 90 degrees and get the same result?
Cheers
