SUMUTE - Surgically Muting Data

The last collection of programs perform a form of crude muting of the data. For a more precise muting operation, there is ``sumute'' which can perform surgical muting of SU data. The program may be used by specifying trace header field to mute on via the ``key='' parameter,
% sumute <indata.su >outdata.su key=KEYWORD xmute=x1,x2,x3,... tmute=t1,t2,t3,... 		
An suplane data example of this is to compare original suplane data, made by
% suplane | suxwigb &
with surgically muted data
% suplane | sumute key=tracl xmute=1,10,12 tmute=.06,.1,.11 | suxwigb &
This says to mute every arrival above the polygonal curve defined by the curve defined by the xmute= and tmute= values.

The program also permits the x,t values to be input from binary files by setting the options ``nmute, xfile, and tfile'' as listed in a portion of the selfdoc for this program

...
 nmute=		number of x,t values defining mute		
 xfile=		file containing position values as specified by	
 			the `key' parameter				
 tfile=		file containing corresponding time values (sec)	
...
 				=tracl  use trace number instead	
 ntaper=0		number of points to taper before hard		
			mute (sine squared taper)			
 below=0		=1 to zero BELOW the polygonal curve		
...
Please note also that ``above'' and ``below'' refer to the appearance on a seismic plot, such as the suxwigb plot and not to the time values.
