Background material
- IAU definition of Stokes Parameters
They are found here. Radioastronomy, including the 30m telescope, uses these definitions. Note however that according to this definition the sign of Stokes V is opposite to the convention in classical optics as described by Born & Wolf in "Classical Optics"
