How can the jet length to be determined? In my very limited understanding jet is a continuous stream of particles/radiation. Doesn't it continue forever, unless the flow hits some barrier?
I guess it's similar to determining where the sun's atmosphere ends and the solar system begins, or where earth's atmosphere ends. You have to draw a line somewhere.
If the jet only turned on a finite time ago, then it will only have gotten so far in that time, so it will have a length = (jet velocity) * (time jet has been active).
