Synopsis
        sfgazdag < in.rsf > out.rsf velocity=vel.rsf velz=velz.rsf eta=eta.rsf inv=n eps=0.01 verb=n depth=n nt= dt= nz= dz= vel= vz=v0 n=0.0 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=
Sampling of depth axis (for migration, if no velocity file)
 
float eps=0.01
stabilization parameter
 
string eta=
auxiliary input file name
 
bool inv=n [y/n]
if y, modeling; if n, migration
 
float n=0.0
Constant eta (if no velocity file)
 
int nt=
Length of time axis (for modeling)
 
int nz=
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=
auxiliary input file name
 
string velz=
auxiliary input file name
 
bool verb=n [y/n]
verbosity flag
 
float vz=v0
Constant vertical velocity (if no velocity file)
