2-D Prestack Kirchhoff time migration with antialiasing.

 
Synopsis
        sfmig2semb < inp.rsf vel=vel.rsf > out.rsf semblance=semblance.rsf gather=gather.rsf offset=offset.rsf adj=y normalize=y nh= antialias=1.0 apt=nx angle=90.0 half=y verb=y rho=1.-1./nt dh= h0=
The axes in the input are {time,midpoint,offset}
The axes in the offset are {1,midpoint,offset}
The axes in the output are {time,midpoint}
The axes in the "image gather" are {time,midpoint,offset}

 
Parameters
       
 
bool adj=y [y/n]
adjoint flag (y for migration, n for modeling)
 
float angle=90.0
angle aperture
 
float antialias=1.0
antialiasing
 
int apt=nx
integral aperture
 
float dh=
offset sampling (for modeling)
 
string gather=
auxiliary output file name
 
float h0=
first offset (for modeling)
 
bool half=y [y/n]
if y, the third axis is half-offset instead of full offset
 
int nh=
number of offsets (for modeling)
 
bool normalize=y [y/n]
normalize for the fold
 
string offset=
auxiliary input file name
 
float rho=1.-1./nt
Leaky integration constant
 
file semblance=
auxiliary output file name
 
file vel=
auxiliary input file name
 
bool verb=y [y/n]
verbosity flag
