SUGPRFB - SU program to remove First Breaks from GPR data

 sugprfb < radar traces >outfile			  		

nx=51		number of traces to sum to create pilot trace (odd)	
fbt=60	length of first break in number of samples		

Notes:								
The first fbt samples from nx traces are stacked to form a pilot	
first break trace, this is fitted to the actual traces by shifting	
and scaling.		 The nx traces long spatial window is		
slided along the section and a new pilot traces is formed for each	
position. The scalers in percent and the time shifts are stored in	
header words trwf and grnors.
