Re: (meteorobs) population index Leonid storms
Hello Michel,
> To do our ZHR calculations of the Leonid meteor storm (7 REV), I have the following question ; is there already a reliable population index calculated for this storm ??
The population index resulting from the analysis just in print for WGN
showed a relatively high peak in r of about 2.5. Here is an extract of
results for the 7-rev trail (European). Note that r looks smooth because
it's from interpolation of a coarser r-graph which I don't have in
tabular form here.
