Our model provides the time of the passages (Cols.~1--3), Zenithal Hourly Rate
(ZHR; Col.~4), duration (Col.~5) and particle flux (Col.~6) as predicted by our model. The calculated ZHR applies to the atmosphere of the Earth \citep{Jenniskens94}.
The Duration~$\times$ Flux product (Col.~7) gives the cumulative flux.
