Heterodyne
----------
The heterodyne sensor type allows to model a generic heterodyne radio receiver which uses an local oscillator and an mixer to create spectral images. The heterodyne-component contains several parameters which are explained in the following. All parameters are defined according to the `Guide to GREAT <https://www.sofia.usra.edu/science/proposing-and-observing/observers-handbook-cycle-9/6-great/61-specifications#PerformanceGREAT>`_.
