(meteorobs) Re: Question about radiant drift

[Sergey Shanov]

What before you stands the task? You know a position radiant for date? Can
be then on this radiant it is necessary to define an orbit. And already
knowing an approximate orbit it is possible to define a drift radiant. So?
What exactitude is necessary?
