(meteorobs) Size of radiants.

[Robert J. Gardner]

Thank you Marco, Roberto and Al for your replies. Actually you answered 
the question as I asked it, however I asked the wrong question. What I 
had assumed was that the radiant is not a well defined point but is a 
circle or ellipse from which the overwhelming majority of the meteors of 
a particular shower radiate. I intended to ask the question of how large 
is that circle. I have since assumed that ten degrees would be too large 
for such a circle, but I would still like to propose the question, how 
large is are radiants in general?
