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:

1. 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

OUTPUT:

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