The inline comments and other documention for twavpol should make it clear that the input needs to be in field aligned coordinates.

Also, that the helicity and ellipticity are both signed, indicating LH vs RH polarization. It is possible that the two quantities should be defined with opposite signs, which would call for a change in the current code (C. Chaston has been asked to weigh in on this).

We need these for both IDL SPEDAS and PySPEDAS.
