cpx = complex values; alternating real and imaginary pixels
rmg = alternating lines of amplitude and phase

BSQ = band sequential
BIL = band interleave


File Names:
Important files created during the processing are listed below.  Not all of the files listed are created during every processing scenario.   For example, additional files are created when you include a seismic model in the processing.  Capital letters designate where names will vary according to the input parameters in date1-date2.proc
