Post-stack 2-D v(z) time modeling/migration with Gazdag phase-shift.

 
Synopsis
        sfgazdag < in.rsf > out.rsf velocity=vel.rsf inv=n eps=0.01 depth=n nt= dt= nz=nt dz=dt vel= pad=2*kiss_fft_next_fast_size((nt+1)/2) rule=

 
Parameters
       
 
bool depth=n [y/n]
if true, depth migration
 
float dt=
Sampling of time axis (for modeling)
 
float dz=dt
Sampling of depth axis (for migration, if no velocity file)
 
float eps=0.01
Stabilization parameter
 
bool inv=n [y/n]
If y, modeling; if n, migration
 
int nt=
Length of time axis (for modeling)
 
int nz=nt
Length of depth axis (for migration, if no velocity file)
 
int pad=2*kiss_fft_next_fast_size((nt+1)/2)

 
string rule=
phase-shift interpolation rule (simple, midpoint, linear)
 
float vel=
Constant velocity (if no velocity file)
 
string velocity=
file with velocity (auxiliary input file name)
