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.

Python

The Python package PyHFC offers simple tools to query the HFC database and to plot the feature contours over the solar images.

IDL

The HELIO IDL SolarSoft package provides routines to query and plot HFC feature data.

In addition, a stand-alone software for users who want to get only the HFC content using IDL can be downloaded here. Please read the dedicated user guide for more details.

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 ended on 30th November 2012.
