actionAngleStaeckel

class galpy.actionAngle.actionAngleStaeckel(*args, **kwargs)[source]

Action-angle formalism for axisymmetric potentials using Binney (2012)’s Staeckel approximation

__init__(*args, **kwargs)[source]

Initialize an actionAngleStaeckel object.

Parameters:
  • pot (potential or list of potentials (3D)) – The potential or list of potentials.

  • delta (float or Quantity) – The focus.

  • useu0 (bool, optional) – Use u0 to calculate dV (not recommended). Default is False.

  • c (bool, optional) – If True, always use C for calculations. Default is False.

  • order (int, optional) – Number of points to use in the Gauss-Legendre numerical integration of the relevant action, frequency, and angle integrals. Default is 10.

  • ro (float or Quantity, optional) – Distance scale for translation into internal units (default from configuration file).

  • vo (float or Quantity, optional) – Velocity scale for translation into internal units (default from configuration file).
