Re: (meteorobs) Angular Speed Equations

 As Malcolm pointed out, a good angular speed measurement can be used to
 roughly estimate the shower radiant position, when combined with the path
 length.  >>

Yes this can be done for one meteor if desired. But why would you want to 
find a rough estimate for a "shower radiant position" with just one meteor? I 
don't know anyone who seriously looks for a shower radiant position with just 
one meteor in the first place. Meteor intersects is what people look for 
initially when looking for possible new radiants. If you have 2 or more 
meteors that intersects to give one a reason to think about a possible 
radiant position, the position area becomes obvious.  This can be done with 
the speed scale I use. For new possible radiants though, Usually no one gives 
a second look until they have at least about 4 intersects per 50 plotted 
meteors whether one uses angular velocity estimates or a speed scale.  
Anything less, you will end up with thousands of "new radiants" each year to 
needlessly burden yourself with.
