21 The Circular representation of polarisation.
22 NOTE U and V are probably wrong
23 We are using the following convention:
24 @li I = RR + LL
25 @li Q = RR - LL
26 @li U = 2*Real(RL)
27 @li V = 2*Imag(RL)
28
29 resulting in:
30 @li I' = I
31 @li Q' = Q * cos(theta) - V *sin(theta)
32 @li U' = Q * sin(theta) + U * cos(theta)
33 @li V' = V
