Astronomy.orbits3D.orbit_vector(ax, maxval, long_asc_node, inclination, longitude, npts, line_format)

Draw a radial vector

The vector is drawn outwards from the center along a plane which intersects the xy plane at the longitude of the ascending node with the specified inclination. The longitude of the vector in this plane is measured from the intersection.

:param maxval : radius :type maxval : float

:param long_asc_node : longitude (deg) where vector crosses the orbit :type long_asc_node : float

:param inclination : tilt (deg) of the orbital axis :type inclination : float

:param longitude : longitude measured on inclined plane from intersection :type longitude : float (degrees)

:param npts : number of points :type npts : int

:param line_format : standard matplotlib symbol code, like “k-” :type line_format : str
