# galpy.orbit.Orbit.Lz¶

Orbit.Lz(*args, **kwargs)[source]

NAME:

Lz

PURPOSE:

calculate the z-component of the angular momentum at time t

INPUT:

t - (optional) time at which to get the angular momentum (can be Quantity)

ro= (Object-wide default) physical scale for distances to use to convert (can be Quantity)

vo= (Object-wide default) physical scale for velocities to use to convert (can be Quantity)

use_physical= use to override Object-wide default for using a physical scale for output

OUTPUT:

z-component of the angular momentum [*input_shape,nt]
