fit_harmonic_oscillator¶

gala.dynamics.fit_harmonic_oscillator(orbit, omega0=[1.0, 1.0, 1.0])[source]

Fit the toy harmonic oscillator potential to the sum of the energy residuals relative to the mean energy by minimizing the function

$f(\boldsymbol{\omega}) = \sum_i (\frac{1}{2}v_i^2 + \Phi_{\rm sho}(x_i\,|\,\boldsymbol{\omega}) - <E>)^2$
TODO: This should fail if the Hamiltonian associated with the orbit has
a frame other than StaticFrame
Parameters: orbit : Orbit omega0 : array_like (optional) Initial frequency guess. omegas : float Best-fit harmonic oscillator frequencies.
