actionAngleIsochroneInverse

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

Inverse action-angle formalism for the isochrone potential, on the Jphi, Jtheta system of Binney & Tremaine (2008); following McGill & Binney (1990) for transformations

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

Initialize an actionAngleIsochroneInverse object.

Parameters:

  • b (float or Quantity, optional) – Scale parameter of the isochrone parameter.

  • ip (galpy.potential.IsochronePotential, optional) – Instance of a IsochronePotential.

  • 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).

Notes

  • Either specify b or ip.
