find_actions¶
- gala.dynamics.find_actions(orbit, N_max, force_harmonic_oscillator=False, toy_potential=None)¶
Deprecated since version v1.5: The find_actions function is deprecated and may be removed in a future version. Use find_actions_o2gf instead.
Find approximate actions and angles for samples of a phase-space orbit. Uses toy potentials with known, analytic action-angle transformations to approximate the true coordinates as a Fourier sum.
