B Where Can I Find a Barycentric Solar System Ephemeris?

[Dale]

Does anyone know of a website with an accurate ephemeris where you can plug in a time and get the state vectors (position and velocity) for the sun and all of the planets in a barycentric coordinate system?

Will this site do the trick?

Thanks, this seems to be just about perfect!

For observer location, use @0 for barycentric or @010 for heliocentric.
There won't be a huge difference between the two.
I find heliocentric more useful.

Thanks for the tip. I need barycentric because I am calculating angular momentum and I don't want to have to adjust things for the wobbling of the sun.
