Ray tracing by a Runge-Kutta integrator.

 
Synopsis
        sfrays2 < vel.rsf > rays.rsf shotfile=shots.rsf anglefile=angles.rsf vel=y order=4 nt= dt= sym=y verb=y escvar=n zshot=0. yshot=o[1] + 0.5*(n[1]-1)*d[1] nr= a0=0. amax=360. > rays.rsf
Rays can be plotted with sfplotrays.

 
Parameters
       
 
float a0=0.
minimum angle (if no anglefile)
 
float amax=360.
maximum angle (if no anglefile)
 
string anglefile=
file with initial angles (auxiliary input file name)
 
float dt=
Sampling in time
 
bool escvar=n [y/n]
If y - output escape values, n - trajectories
 
int nr=
number of angles (if no anglefile)
 
int nt=
Number of time steps
 
int order=4
Interpolation order
 
string shotfile=
file with shot locations (auxiliary input file name)
 
bool sym=y [y/n]
if y, use symplectic integrator
 
bool vel=y [y/n]
If y, input is velocity; if n, slowness
 
bool verb=y [y/n]
Verbosity flag
 
float yshot=o[1] + 0.5*(n[1]-1)*d[1]

 
float zshot=0.
shot coordinates (if no shotfile)
