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.
