galpy.orbit.Orbit.LcE¶

Orbit.LcE(*args, **kwargs)[source]¶

Calculate the angular momentum of a circular orbit with the same energy.

Parameters:

t (numeric, numpy.ndarray or Quantity, optional) – Time at which to get the radius. Default is the initial time.
pot (Potential or list of Potential instances, optional) – Gravitational potential. Default is the gravitational field used for the orbit integration.
ro (float or Quantity, optional) – Physical scale in kpc for distances to use to convert. Default is object-wide default.
vo (float or Quantity, optional) – Physical scale in km/s for velocities to use to convert. Default is object-wide default.
use_physical (bool, optional) – Use to override object-wide default for using a physical scale for output.
quantity (bool, optional) – If True, return an Astropy Quantity object. Default from configuration file.

Returns:

Angular momentum of a circular orbit with the same energy.

Return type:

float, numpy.ndarray or Quantity [*input_shape]
