Re: [find_orb] impacts

Hi Tomas,

Looks as if I need to add a step in that section of the documentation:
you have to go into Settings, and make sure that the 'heliocentric orbits
only' box is not checked. By default, it's unchecked. But every now
and then, one does need heliocentric elements, even though logic would
suggest planetocentric ones... I usually run into that situation when
I want to generate elements for use in software that requires heliocentric
data.

The elements you got look to be exactly right, except for being
heliocentric instead of geocentric. Turn off that check-box, and
set the epoch to 7.12 October (closer to the impact time), and perhaps
adjust the collision altitude, and you should get the right impact point.
