galpy.actionAngle.actionAngle.actionsFreqsAngles

actionAngle.actionsFreqsAngles(*args, **kwargs)

Evaluate the actions, frequencies, and angles (jr,lz,jz,Omegar,Omegaphi,Omegaz,angler,anglephi,anglez)

Parameters:

• *args (tuple) –

  Either: a) R,vR,vT,z,vz,phi:

  1. floats: phase-space value for single object (phi is optional) (each can be a Quantity)

  2. numpy.ndarray: [N] phase-space values for N objects (each can be a Quantity)

  2. Orbit instance: initial condition used if that’s it, orbit(t) if there is a time given as well as the second argument

• **kwargs (dict) – Additional keyword arguments to be passed to _actionsFreqsAngles method.

Returns:

(jr,lz,jz,Omegar,Omegaphi,Omegaz,angler,anglephi,anglez)

Return type:

tuple
