Moving object potential

class galpy.potential.MovingObjectPotential(orbit, pot=None, amp=1.0, ro=None, vo=None)

Class that implements the potential coming from a moving object by combining any galpy potential with an integrated galpy orbit.

__init__(orbit, pot=None, amp=1.0, ro=None, vo=None)

Initialize a MovingObjectPotential.

Parameters:

• orbit (galpy.orbit.Orbit) – The orbit of the object.

• pot (Potential object or list of Potential objects) – A potential object or list of potential objects representing the potential of the moving object; should be spherical, but this is not checked. Default is PlummerPotential(amp=0.06,b=0.01).

• amp (float, optional) – Another amplitude to apply to the potential. Default is 1.0.

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

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