h2. HFC (Heliophysics Features Catalogue)

HFC holds table for Filaments, Active Regions and Coronal Holes, as well as for filament tracking.

It will be updated for Active Regions before the end of February 2011 and, at the beginning of March 2011 for type III radio bursts.

A very rough access to it is available at:

http://bass2000.obspm.fr/helio-fc/search_wiz.php

and a GUI is being developed. A very preliminary prototype is available at:

http://bass2000.obspm.fr/helio-fc/gui/index.php

In March, HFC will be moved on a virtual machine of Virtual Observatory Paris Data Centre, maintained 7/7, 24/24 and 365/365, mirrored in Paris and in Meudon (suburb of Paris), avoiding the risk of network problems.

Status of HFC can be followed through:

and Web Services appear on:

Discussion is in progress on the way to connect HFC to the rest of the HELIO system. Probably a good solution could be to have an external access through a specific GUI, which provides a VOTable output used as an input by the HELIO Front End.

h2. Propagation

Discussions concerning propagation model are still in progress. An inventory of propagation models has been written by UPST partner while TCD partner proposes a very simple ballistic model that can be used for test. As for HFC, the best place to apply propagation models is still under discussion.

h2. Standards

An attempt to apply SPASE (http://www.spase-group.org/) Data Model is in progress, in order to describe solar observation. It seems to fit quite well our needs. But it may fail at linking observations/data together.
