Using start date and end date all shock events at Earth are backpropagated to the Sun.
Arround the time all flares (above certain levels) and cmes are assoicated.
The possition of the flare and speed of the CME are used to forward propagate the event to Mars.

This is the implementation of a use case worked on during CDAW3 of the HELIO project.
SEP events propagated backward from Earth to the Sun. We allow for +- 30 min around the predicted time to search for flare events. The timing of the flare event informs the search time for Type III radio event (time_start to time_peak) and for the CME event (time_start to time_start+1h).
Results are presented in a mulitlayered VOTable.
