 SUTAPER - Taper the edge traces of a data panel to zero.	


 sutaper <stdin >stdout [optional parameters]		  

 Optional Parameters:					  
 ntr=tr.ntr	number of traces. If tr.ntr is not set, then	
 		ntr is mandatory				
 tr1=0	 number of traces to be tapered at beginning	
 tr2=tr1	number of traces to be tapered at end		
 min=0.		minimum amplitude factor of taper		
 tbeg=0		length of taper (ms) at trace start		
 tend=0		length of taper (ms) at trace end		
 taper=1	taper type					
		 =1 linear (default)			   
		 =2 sine					
		 =3 cosine					
		 =4 gaussian (+/-3.8)			  
		 =5 gaussian (+/-2.0)			  

 Notes:							
   To eliminate the taper, choose tbeg=0. and tend=0. and tr1=0
