Here is the SSC definition of the sky beams

And below is a similar view of the radiometer platform showing also the primary mirror and the subreflector.

The sky beam directions are shown as 6 lines. The Red and White indicate the defined and calculated beam directions. The calculated beam direction is based on the rotation of the calibration switch mirror. The defined beam direction is the one defined in the SSC image above.

The yellow lines show the erroneous direction that was used in the quasioptics design.

19 skybeams
