DATA SEGY TAPE FORMAT:

 3200 byte	SEGY REEL HEADER #1
  400 byte	SEGY REEL HEADER #2
16244 byte	DATA TRACES: 40800 seismograms consisting of
			8 stations x 3 components x 1700 seismograms 

		The data was collected as common receiver gathers, but
		is stored as if each CRG is a common shot gather.  The
		data is NOT resorted into actual shot gathers.
