Instrument Parameters and Generation of Interferograms

Once the sky map has been defined both spatial and spectrally, the Double Fourier Modulation can be applied. For this simulation, the baselines are set from bmin = 142 mm to bmax = 392 mm, with a baseline separation of bstep = 5 mm, giving a total of 51 baselines. 

Optical step size of 32 [jun and an oversampling rate of 10 it corresponds to an optical path difference of 0.64 mm, 0.8 mm and 0.96 mm, respectively. In the simtilation, the separation between peaks of the interferograms for the three baselines shown is 0.63, 

Once the interferograms have been generated, one can proceed to extract the spectral and spatial features of the datacube using the algorithms described earUer in this chapter.
