I have an old file "comet00.dat" that has the comet Kohoutek P/75 in it. Here are
the numbers from the file. If you can sort out hte spacing.
P/Kohoutek (75P) 4.3761 11 2007 0.0 1.794054
0.494611 5.9028 175.6906 269.6976 2000.0 10.5 4.0 MPC 31663
Or better still here are the elements that can be used to create a new comet.
Or I can send you the whole file (276K) it has 1649 objects listed. I think it is
the original file in Guide but I replaced it with more up to date comets --
replacing or getting rid of some older "out of place" asteroids and comets.
