 SUMIGGBZO - MIGration via Gaussian Beams of Zero-Offset SU data	

 sumiggbzo <infile >outfile vfile=  nz= [optional parameters]		

 Required Parameters:							
 vfile=                 name of file containing v(z,x)			
 nz=                    number of depth samples			

 Optional Parameters:							
 dt=from header		time sampling interval			
 dx=from header(d2) or 1.0	spatial sampling interval		
 dz=1.0                 depth sampling interval			
 fmin=0.025/dt          minimum frequency				
 fmax=10*fmin           maximum frequency				
 amin=-amax             minimum emergence angle; must be > -90 degrees	
 amax=60                maximum emergence angle; must be < 90 degrees	
 bwh=0.5*vavg/fmin      beam half-width; vavg denotes average velocity	
 verbose=0		 =0 silent; =1 chatty				

 Note: spatial units of v(z,x) must be the same as those on dx.	
 v(z,x) is represented numerically in C-style binary floats v[x][z],	
 where the depth direction is the fast direction in the data. Such	
 models can be created with unif2 or makevel.
