Simulation of “frequency switching”.

A general method for frequency switching. The WSM sensor_responseBackendFrequencySwitching() gives a description of this observation technique, and is also a more straightforward method for pure singel sideband cases.

It is here assume that sensor_responseMultiMixerBackend() has been used to calculate the spectrum for two LO positions. This method calculates the difference between these two spectra, where the second spectrum gets weight 1 and the first weight -1 (as in sensor_responseBackendFrequencySwitching()).

Output frequency grids are taken from the second spectrum.
