Split VOTable into its values (1)

• Download

This workflow takes a single VOTable and splits it up in a vector for the names of fields, a vector for the UCDs of the fields, a vector for the UTypes of the fields, and a two dimensional vector for the values.

• Download

Run the cir backwards propagation code on the HELIO processing service. Required inputs: time start of backwards propagation, the object (planet/spacecraft) from where the propagation should start, assumed solar wind speed at the time, assumed error of solar wind speed Output: VOTable with times at different points in solar system

• Download

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.

• Download

This workflow uses the initial time period to search for time periods where Earth and Mars are not further appart than 80 degrees. These time periods are used to find Halo CME events. The CME events are forward propagated to Earth and Sun. Only events were the propagation model predicts that both planets are on the propagation path will be included in the final VOTable
