Comment 6 for bug 1405460

I think Alexander is right. I imported the elements from MPC list import, not the online search. Comet element sets should NOT have orbit_MeanAnomaly or orbit_MeanMotion entries, these don't make much sense for most comets!

So this is a duplicate of the bug which Alexander mentioned above. Do NOT comment away the test in line 463, or you risk a massive slowdown if you have many element sets.

These would be the elements if imported via list import, and these work:
