[net.astro] Request for Halley Orbitals

I am preparing to modify a program that displays the positions of
the sun, moon, planets, and stars brighter than magnitude 4.0 to
include Halley's Comet. Would someone post the latest orbital parameters
for Halley's Comet? I need the following:

	Semi-major Axis (a.u):
	Mean Motion (rad/day):
	Eccentricity (rad):
	Inclination (rad):
	Right Ascension of Ascending Node (rad):
	Argument of Perihelion (rad):
	Mean Anomaly at Epoch (rad):
and of course the Epoch for the orbitals.
