n3-int
      [1] 1 = traveltime map
      2 = traveltime and amplitude map
      6 = traveltime, amplitudes and propagation angles
v0-real
      velocity at z=0  : v0 >= 0
vgrad-real

DESCRIPTION

        Code to calculate Green's function traveltime and
        ~amplitude for a 1-D constant gradient velocity model:
                        V(z) = Vo + vgrad*z     ;  z >= 0,  vgrad >= 0
