In this chapter the processing of step S_FILTAZI is described. Normally the step S_FILTAZI is performed at the same time as M_FILTAZI. (PROCESS M_FILTAZI card in input file.) However, we kept this two seperate steps to be able to only filter the slave images in a large stack (all slaves coregistered on the same master image). This has the advantage that for each interferogram of the stack not a large file is created for the master. The disadvantage of not filtering the master of course is that a small part of the spectrum of the master is not shared with the slave spectrum, yielding coherence loss of the interferogram.

Further information on the input/output of this step can be found in Chapter 15 (M_FILTAZI).
