- 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"
- The sign of Stokes V
in 30m observations with XPOL has been determined through several methods. They are described in this short note.
