Hi Nicolas,

Thanks for posting these orbital elements. Just thought I'd mention
that they can be used as follows:

(1) Save the file,

http://groups.yahoo.com/group/guide-user/files/73Pfragments.txt

in your Guide folder.

(2) Start up Guide, and click on Extras... Add MPC
Comets/Asteroids. Scroll to the bottom of the resulting text, and
click on "Add MPC Comets/Asteroids".

(3) Selet the '73Pfragments.txt' file.

Guide will automatically load the elements, just as if they had
come from the MPC site.
