A friend has created a new "add_mpc.hee" that points to the alternate website of

directly into this e-mail. So just copy everything between the pair of double lines
below and replace the "add_mpc.hee" file in your guide folder. I checked it and it
works fine.

using both sources; MPC gives currently-observable comets, IMCCE all
comets since about 1995. (Data for historical comets is already built
into the Guide DVD.) You can click on the following to download
some of these files, getting orbital data for newly-found objects and
improving orbits for already known objects. About 600 KBytes will be

Guide can also import other orbital elements if they're provided in
the "eight-line format", or the "one-line format" used for Daily Orbit
Updates. You wouldn't normally do this, but if you have generated an
orbit using Find_Orb, for example, you could import the resulting file
of orbital elements using the following command.
d soft02cm.txt
