While I can't reproduce them on demand, the console log
produced by Celestia 1.3.2 final
sometimes displays a long list of three numberic values
before it mentions extras/minormoons.ssc
Presumably they're debugging output for something that doesn't happen
Celestia screenshots displaying this are available:
shows the start. There was no ouput before what's shown.
shows the end of them. There were no more after minormoons.ssc
I have Grant's basicextrasolars.stc installed, so there are
no error messages from extrasolars.ssc. I've seen these
numbers appear once before when I wasn't using basicextrasolars.stc.
