2-D forward modeling to generate shot records

 
Synopsis
        sfmodeling2d < vinit.rsf > shots.rsf time=time.rsf check=check.rsf chk= kt=100 amp=1000 fm=10 dt= nt= ns= ng= jsx= jsz=0 jgx=1 jgz=0 sxbeg= szbeg= gxbeg= gzbeg= csdgather=n
Note: Clayton-Enquist absorbing boundary condition (A2) is applied!

 
Parameters
       
 
float amp=1000
maximum amplitude of ricker
 
file check=

bool chk= [y/n]

 
bool csdgather=n [y/n]
default, common shot-gather; if n, record at every point
 
float dt=
time interval
 
float fm=10

receiver z-axis jump interval
 
int jsx=
source x-axis jump interval
 
int jsz=0
source z-axis jump interval
 
int kt=100
check it at it=100
 
int ng=
total receivers in each shot
 
int ns=
total shots
 
int nt=
total modeling time steps
 
int sxbeg=
x-begining index of sources, starting from 0
