Workspace Method sensor_responseFrequencySwitching
Description
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..
