Note: It is used as a demonstration that we can reconstruct the modeled
wavefield exactly via boundary saving.

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=

int ns=1
total shots
int nt=
total modeling time steps
int sxbeg=
x-begining index of sources, starting from 0
