Forward-backword exact reconstruction using boundary saving

 
Synopsis
        sffbrec < vinit.rsf > Fw1.rsf back=Fw2.rsf amp=1000 fm=10 dt= nt= ns=1 ng= jsx= jsz=0 jgx=1 jgz=0 sxbeg= szbeg= gxbeg= gzbeg= csdgather=y ft=0 jt=1
Note: It is used as a demonstration that we can reconstruct the modeled
wavefield exactly via boundary saving.

 
Parameters
       
 
float amp=1000
maximum amplitude of ricker
 
file back=
auxiliary output file name
 
bool csdgather=y [y/n]
default, common shot-gather; if n, record at every point
 
float dt=
time interval
 
float fm=10
dominant freq of ricker
 
int ft=0
first recorded time
 
int gxbeg=
x-begining index of receivers, starting from 0
 
int gzbeg=
z-begining index of receivers, starting from 0
 
int jgx=1
receiver x-axis jump interval
 
int jgz=0
receiver z-axis jump interval
 
int jsx=
source x-axis jump interval
 
int jsz=0
source z-axis jump interval
 
int jt=1
time interval
 
int ng=
total receivers in each shot
 
int ns=1
total shots
 
int nt=
total modeling time steps
 
int sxbeg=
x-begining index of sources, starting from 0
 
int szbeg=
z-begining index of sources, starting from 0
