21 | The linear representation of polarisation. |

22 | We are using the following convention: |
---|
23 | @li I = XX + YY |
---|
24 | @li Q = XX - YY |
---|
25 | @li U = 2*Real(XY) |
---|
26 | @li V = 2*Imag(XY) |
---|
27 | |

28 | resulting in: |
---|
29 | @li I' = I |
---|
30 | @li Q' = Q * cos(theta) - V *sin(theta) |
---|
31 | @li U' = Q * sin(theta) + U * cos(theta) |
