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.
