 t=0.			array of times for (t,v,eta) triplets (specify more
				than once if needed)			
 v=1500.		array of velocities for (t,v,eta) triplets (specify
				more than once if needed)		
 eta=0.		array of etas for (t,v,eta) triplets (specify more
				than once if needed)			

 Note: This is a simple research code based on linear interpolation.	
 There are no protections against aliasing built into the code beyond	
 suggesting that this program have a knowledgable user. A final version
 should do a better job taking care of endpoint conditions.

    sugabor <stdin >stdout [optional parameters]			

 Required parameters:					 		
	if dt is not set in header, then dt is mandatory		

 Optional parameters:							
	dt=(from header)	time sampling interval (sec)		
	fmin=0			minimum frequency of filter array (hz)	
	fmax=NYQUIST 		maximum frequency of filter array (hz)	
	beta=3.0		ln[filter peak amp/filter endpoint amp]	
	band=.05*NYQUIST	filter bandwidth (hz) 			
	alpha=beta/band^2	filter width parameter			
	verbose=0		=1 supply additional info		
	holder=0		=1 output Holder regularity estimate	
				=2 output linear regularity estimate	

 Notes: This program produces a muiltifilter (as opposed to moving window)
 representation of the instantaneous amplitude of seismic data in the	
 time-frequency domain. (With Gaussian filters, moving window and multi-
 filter analysis can be shown to be equivalent.)
