    • The structure for this workshop will allow participants to interact and to get involved in working on some of the data, analysis techniques and identified issues. There will be several oral presentations, which will form the backbone of our workshop. These will provide an overview of the various ESA IPY projects, their current status as well as of the analysis techniques applied.

    Presentations, free discussions and demonstrations on project related topics are scheduled for this workshop.
