actionAngle (galpy.actionAngle)

(x, v) –> (J, O, a)

General instance routines

Not necessarily supported for all different types of actionAngle calculations. These have extra arguments for different actionAngle modules, so check the documentation of the module-specific functions for more info (e.g., ?actionAngleIsochrone.__call__)

In addition to the methods listed above, actionAngleTorus also has the following methods:

Warning

While the actionAngleTorus code can compute the Jacobian and Hessian of the (J, a) –> (x, v, O) transformation, the accuracy of these does not appear to be very good using the current interface to the TorusMapper code, so care should be taken when using these.
