First, choose a time range int the "Date and time selection" tab
Then, select the Feature(s) for which you want data using the "Feature selection" tab. For a single feature, you can specify other criteria than date using the dropdown menu of the "Extended criteria" box
For each selected feature, you may specify one or more "Observatory" (use Ctrl key to multiselect). The query will apply only on features detected from observations of the selected Observatory.
Finally, enter the type(s) of output requested in the "Output options" tab. For each feature, you can also include optional parameters in the results page using corresponding "Optional fields" tab.

The catalog can also be queried by distant web service clients using the dedicated Helio Query Interface (HQI). WSDL files that describe the types of request permitted can be found at:

http://voparis-helio.obspm.fr/helio-hfc/HelioService

The HQI allows PQL queries in the HFC database (more information about PQL can be found here).

The "Database and fields description" page gives a description of the fields readable in the database.

Feedback

The HFC is still under development, so any feedback is much appreciated. Please send your comments to Jean dot Aboudarham at obspm dot fr and Christian dot Renie at obspm dot fr.

About the HELIO project

The HFC is a service of the Heliophysics Integrated Observatory HELIO, a virtual observatory dedicated to solar and heliophysics.

HELIO is a Research Infrastructures funded under the Capacities Specfific Programme within the European Commission's Seventh Framework Programme (FP7, project No. 238969). The project started on 1st june 2009 and has a duration of 36 months.
