Workspace Method sensor_responsePolarisation
Description
Extraction of non-default polarisation components.
The default is to output the Stokes elements I, Q, U and V (up to
stokes_dim). This method allows to change the "polarisation" of
the output. Polarisation components to be extracted are selected by
sensor_pol. This method can be applied at any step of the sensor
matrix set-up.
The method can only be applied on data for I, Q, U and V. The value
of stokes_dim must be sufficiently large for the selected
components. For example, I+45 requires that stokes_dim is at
least 3.
See sensor_pol for coding of polarisation states.
Note that the state of iy_unit is considered. This WSV must give
the actual unit of the data. This as, the extraction of components
is slightly different if data are radiances or brightness
temperatures. In practise this means that iy_unit (as to be
applied inside iy_main_agenda) must be set before calling this
method.
