[1007] | 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)
|

[904] | 27 |
|

[1007] | 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)
