galport.Hamiltonian.fix_points

Hamiltonian.fix_points(J_range=[0.001, 0.5], Nstart=100, t=None, tol=0.01)[source]
Parameters:

  • J_range (list, optional) – range of actions, by default [0.001, 0.5]

  • Nstart (int, optional) – number of initial points on the grid, by default 100

  • t (float, optional) – time, by default None

  • tol (float, optional) – tolerance between roots, by default 10**-2

Returns:

  • fix_point (dict) – J, theta, type(stable, unstable), H, librating time

  • The fixed points are found on the linear grid by angle and

  • logarithmic grid by action.
