fit_isochrone¶
- gala.dynamics.fit_isochrone(orbit, m0=200000000000.0, b0=1.0, minimize_kwargs=None)[source]¶
Fit the toy Isochrone potential to the sum of the energy residuals relative to the mean energy by minimizing the function
\[f(m, b) = \sum_i (\frac{1}{2}v_i^2 + \Phi_{\rm iso}(x_i\,|\,m, b) - <E>)^2\]- TODO: This should fail if the Hamiltonian associated with the orbit has
a frame other than StaticFrame
