(meteorobs) Re: [IMO-News] 2003 Leonid prediction paper



Many thanks for Rainer's efforts to publish the paper on the internet prior
to the shower.

Here, I'm just trying to give the corresponding quantitative population
index for each event predicted. I did not check the prediction as for
Perseids this year, so have no idea for predictions without Da_0 since they
are necessary for the calculation.

The calculated population indices for too old trails or strongly resonant
trails (e.g. 1533) may have some bias.
Also note that these values are for INDIVIDUAL trail only. Other structures
(e.g. so-called filament) and the background may affect it. Though the
influence for strong events is rather weak, but is fairly notable for week
ones, depending on their ZHR.
