Re: (meteorobs) Re: Radiant Diameters

<< 
 These diameters were derived from the plotting errors of experienced
 observers and are based on doubly plotted meteors. The IMO Calendar does
 not list the diameters of 5deg anymore, since thy have no practical
 meaning. The physical diameter is smaller, and the diameter applicable to
 the shower association of visual plots is larger, typically between 15 and
 20 deg as listed above.
 
 I hope I started to clarify the mystery of radiant sizes.
