isochrone_aa_to_xv

gala.dynamics.isochrone_aa_to_xv(actions, angles, potential)[source]

Transform the input actions and angles to cartesian position and velocity coordinates in the Isochrone potential. See Section 3.5.2 in Binney & Tremaine (2008), and be aware of the errata entry for Eq. 3.225.

Parameters
actionsQuantity
anglesQuantity
potentialgala.potential.IsochronePotential, dict

An instance of the potential to use for computing the transformation to angle-action coordinates. Or, a dictionary of parameters used to define an gala.potential.IsochronePotential instance.

Returns
wgala.dynamics.PhaseSpacePosition

The computed positions and velocities.
