kepsnap Compute initial data for 2-body orbit out= Output snapshot with initial data mass1=1.25 Mass of 1st body mass2=1.25 Mass of 2nd body r_peri=0.5 Separation along X at pericenter. Use negative value to reverse Jz, zero value for head-on encounter. eccent=0.6 Eccentricity of orbit (if r_peri != 0). 0 => circle; 1 => parabola. etot=1.0 Total energy of orbit (if r_peri == 0) t_peri=1.0 Time until pericenter nsteps=2048 LF integration steps thetaz=0.0 Angle to rotate results about Z VERSION=1.0 Josh Barnes 31 October 2002
