Initial conditions for a halo orbit

  1. Jun 27, 2011 #1
    Hey folks I'm looking into halo orbits and I have a question about how to find the initial conditions from the third order approximation solution...

    A good run through of the third order solution calculation is found in this paper.
    The Lindstedt-Poincare part begins on page 15.

    My questions are...

    The final approximation includes the [itex]\tau_1[/itex], [itex]A_x[/itex] and [itex]A_z[/itex] terms. These all contain the small parameter [itex]\epsilon[/itex] which hasn't been given a numerical value so how do I compute [itex]\tau_1[/itex], [itex]A_x[/itex] and [itex]A_z[/itex]?

    This is now solved.
