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 (Jenniskens 1994). The Duration $\times $ Flux product (Col. 7) gives the cumulative flux.
