galpy.orbit.Orbit.TrTp¶
- Orbit.TrTp(pot=None, **kwargs)[source]¶
Calculate the ratio between the radial and azimuthal period Tr/Tphi*pi.
- Parameters:
pot (Potential or list of Potential instances, optional) – Gravitational potential. Default is the gravitational field used for the orbit integration.
type ({'staeckel', 'adiabatic', 'isochroneApprox', 'spherical'}, optional) – Type of actionAngle module to use. Default is ‘staeckel’.
kwargs (+actionAngle module setup) –
- Returns:
Ratio between the radial and azimuthal period Tr/Tphi*pi
- Return type:
float, numpy.ndarray or Quantity [*input_shape]
