Sampling and Readout Module

Finally, to facilitate data reduction and analysis each interferogram is recorded in the astronomical standard FITS (Flexible Image Transport System) format. All the data from a single FTS scan are recorded in a single FITS file, including mefrol-ogy data for both the FTS drive and pointing errors. The header includes all the information needed to calculate the baseline vector. 

Although the simulator is set to operate with a single pixel detector and simple ASCII files could be used to store the data, if a detector array is used this data storage format is more adequate.

Once all the simulated noises are computed, they are added to the interferograms at the Add Noise Module to simulate more realistic measurements. The simulated interferograms are then sent to the Detector Module, where the interferograms are distorted according to the detector effects such as the time response. This interferograms are then sampled and readout at the Sampling and Readout Module, which also stores the data for the data reduction and processing.
