Does anyone have a Celestia .xyz file for the Cassini extended tour?

Supposedly it's designated "Tour PF6h9".

If the extended tour's parameters have been provided to Horizons, you can ask Horizons to generate an xyz trajectory for you.

Horizons does have an ephemeris for the interval, but whether or not it's the final one, I don't know. The designation does imply that it's quite recent:

That ID matches the one for the SPICE kernel files recently made available at NAIF, so I'd guess it's the latest predict for the extended tour.

I was hoping maybe someone had already built an xyz file for use with Celestia. Horizons doesn't really seem very well suited to this task, because of the fixed timestep.

I don't suppose someone with a SPICE version of Celestia might be willing to download the Cassini extended tour from NAIF and generate an xyz file using a Lua script with Celestia?
