Sensor/Polarisation WG
att: Mattias (ME), Patrick (PE), Christian (CM), Claas (CT)

* Short discussion about surface reflection. How the parallel and 
perpendicular planes are defined.

* Scattering amplitude matrix, how is it defined in AUG.

* PE: Important to finish polarisation section in AUG. 

* How do we normalise the polarisation response? If the total intensity is 
measured this has to be considered. It affects interpretation of radiances 
and brightness temperatures.

* ME: Special WSM to deal with total intensity simulations.

* CM described how the AMSU-B scanning is performed with a rotating mirror and 
how this give rise to a rotation of the sensor.

* ME gave a short introductory presenstation of the ARTS sensor concept.

* PE: Need to include a 'dual mixer' possibility in ARTS.

* CM asked for possibility to setup the sensor polarisation response by giving 
ellipticity and rotation angles.

* ME: Examples of sensor control files will be put in arts/doc/examples/
