actionAngleIsochroneApprox

class galpy.actionAngle.actionAngleIsochroneApprox(*args, **kwargs)

Action-angle formalism using an isochrone potential as an approximate potential and using a Fox & Binney (2014?) like algorithm to calculate the actions using orbit integrations and a torus-machinery-like angle-fit to get the angles and frequencies (Bovy 2014)

__init__(*args, **kwargs)

NAME:

__init__

PURPOSE:

initialize an actionAngleIsochroneApprox object

INPUT:

Either:

b= scale parameter of the isochrone parameter

ip= instance of a IsochronePotential

aAI= instance of an actionAngleIsochrone

pot= potential to calculate action-angle variables for

tintJ= (default: 100) time to integrate orbits for to estimate actions

ntintJ= (default: 10000) number of time-integration points
