This mixing model rotates the polarization assuming three spectra, one each for the I, Q, and U Stokes parameters. The I spectrum is unchanged, , and .
Which spectrum is from which Stokes parameter is determined using an XFLTnnnn keyword with values ``Stokes:0'', ``Stokes:1'', or ``Stokes:2'', for I, Q, U, respectively.
The parameters are :
|par1||theta, the polarization rotation angle (degrees)|
