galpy.actionAngle.actionAngle.actionsFreqsAngles¶
- actionAngle.actionsFreqsAngles(*args, **kwargs)[source]¶
NAME:
actionsFreqsAngles
PURPOSE:
evaluate the actions, frequencies, and angles (jr,lz,jz,Omegar,Omegaphi,Omegaz,angler,anglephi,anglez)
INPUT:
Either:
R,vR,vT,z,vz,phi:
floats: phase-space value for single object (phi is optional) (each can be a Quantity)
numpy.ndarray: [N] phase-space values for N objects (each can be a Quantity)
Orbit instance: initial condition used if that’s it, orbit(t) if there is a time given as well as the second argument
OUTPUT:
(jr,lz,jz,Omegar,Omegaphi,Omegaz,angler,anglephi,anglez)
