Currently outputs Stokes parameters in a local "camera" tetrad, and separately Stokes I in the coordinate frame via the definition (full trace of N_coord).
Remains to decide which frame is best here, or whether a tetrad corresponding to the coordinates can be reliably constructed.
Ported forward based on work by Abhishek Joshi.
