AMDA service

1. Time Table manager AMDA service Visualisation module Analysis module Local database Remote database Download module

2. AMDA system User WorkSpace : •new physical parameters • time tables (event lists) • plot layouts • search conditions AMDA local database are saved for future sessions parameters

3. AMDA connection to remote database CDAWeb data @ SPDF Access via WebService Data in CDPP format Access via WebService MAPSKP data @ CESR Access via WebService Vex/MAG data @ IWF Access via WebService THEMIS data @ CDPP NFS mounting CDPP is the European mirror site for the SSL Berkeley database Coming soon

4. Where does CLUSTER encircle the current sheet ? magnetic field magnetic field X coordinate AMDA condition : • X1< -10 Re • BX1 * BX2 * BX3 * BX4 > 0 • min([BX1 BX2 BX3 BX4]) < 0 • max([BX1 BX2 BX3 BX4]) > 0 • Your query : • •position : in the magnetotail • • 2 satellites above the current sheet • 2 satellites below the current sheet

5. Centre de Données de Physique des Plasmas The CDPP (Centre de Données de Physique des Plasmas) was created in 1998 jointly by CNES and CNRS. The CDPP is the French national data centre for natural plasmas of the solar system. It assures the long term preservation of data obtained primarily from instruments built using French resources, and renders them readily accessible and exploitable by the international community. The CDPP also provides services to allow user defined data visualisation, merging, computation, search and extraction on data content (AMDA service). The CDPP is involved in the development of interoperability, and participates in several Virtual Observatory projects. http://cdpp.cesr.fr • References • International collaborations • Europlanet network • Helio proposal • Time-Table Exchange • SPASE

6. Create a Time Table by Conditional Search • Edit your search condition with mathematical functions T/T// > 1 mouse click Define a time interval or choose a Time Table

7. Create a Time Table by Visual Inspection • Record intervals of interest by mouse clicks

8. Time Table Manager Time table may be - exported : text or VOTable (XML IVOA compliant) - imported : text or VOTable from the user disk or URL - modified : extended, shifted, intersected, merged Edit your time table … and share them apply operations

9. On the fly data visualisation from multiple remote databases • WIND CDAWeb DB • CASSINI MAPSKP DB • ACE AMDA local DB • THEMIS THEMIS DB solar wind time lag

10. Analysis : create your own physical parameter • AMDA functions include : • solar wind shift • temporal functions : mean, stdev, … • coordinate transforms mouse click and apply to local and remote DB parameters User WorkSpace • This newly created « user parameter » may be : • - used for conditional search • - visualised • downloaded • Like each parameter from the local or remote DB

11. http://cdpp-amda.cesr.fr • AMDA is an online analysis tool connected to various databases • compute new physical quantities • search for events on data content • visualize and download data Everything you do is kept in your User WorkSpace !
