This workflow looks up all instruments known to have worked during the requested periode of time (ICS), restructures results to make them fit instruments.xsd and requests data for this periode from DPAS.
Result: VOTable with list of URLs to data.

general query to DPAS; it gets a list of instruments and lists for start and stop times;
for a query hessiEC, phoenix2; start times 2001-01-01 00:00:00, 2005-04-01 00:00:00; stop times 2001-01-05 00:00:00, 2005-05-1 00:00:00 it would perform to queries:
hessiEC from 2001-01-01 00:00:00 to 2001-01-05 00:00:00 and phoenix2 from 2005-04-01 00:00:00 to 2005-05-1 00:00:00
There is only one output file with the results from both queries.

This workflow demonstrates the standard query where events for a period of time are requested from the HEC service, available instruments for this time come from the ICS and data only for the times of the events are requested from the DPAS.
In this version data from only 3 random events (out of the HEC list) will be requested from the DPAS.

This workflow is querying the HFC ActiveRegions list and HEC hessi_flare list.
It requires a time periode and a search radius arround the centre of an Active Region as inputs
It produces two outputs: HFCout is a modified VOTable where a field is added with the number of associated hessi flares. combined_output is a 2 dimensional list with an VOTable for each Active region and one with an VOTable for all associated flares for that Active Region.

This workflow takes a type of isnstrument as input and the minimum and maxium coordinates in HCI as input. Cadence for the location service is for defining the 'continues' presence.
Output is a VOTable based on the ICS return where two columns are added for the time this instrument has entered and exited the Region of Interest.

This workflow uses flares listed in the goes_sxf_flare list, checks wether this flare is connected to Earth via the Parker spiral, and looks for proton events at earth listed in the goes_proton_event list.
The flare listing and the proton listing is combinded into a VOTable output.

This workflow uses flares listed in any HELIO HEC flare catalogue (using the semantic mapping service), checks whether these flares are connected to Earth via the Parker spiral, and looks for proton events at earth listed in the goes_proton_event list.
The flare listing and the proton listing are combinded into a list of VOTable outputs (one VOTable per flare catalogue with results).

Workflow propagates an CME event from its observing point (planet/spacecraft) back to the sun.
The propagation also provides the timing of this event at other points in space (planet/spacecraft)

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

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.

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

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.
