1. BASS2000 : status and perspectives Status Projects  New producers  New data types  New THEMIS request  Service to the users  Combined requests between archives Nadège Meunier and the BASS2000 team Observatoire Midi-Pyrénées

2. Status Integrated data:  THEMIS 1999-2001 : 2063 Go (1635 sequences)  NRH 1999-2001 : 192 Go (833 sequences) Requests: mostly PIs and coIs  330 Go in 2001  600 Go in 2000 Consultations of the site : ~ 1080 /month Pedagogic tool:  Lessons for primary school to high school  FAQ

3. New producers The Pic-du-Midi Coronograph The Coupole-Tourelle at the Pic du Midi MSDP-VTT IRIS data

4. New data types Granulation simulation Movies ( MPEG, …) Processed data ( FITS )

5. Granulation simulation 8 « solar » hours Step = 20 seconds Realization : Rieutord, Ludwig, Roudier, Nordlund & Stein image

6. Movies (MPEG) Pic du Midi Coronograph (realization J.-C. Noëns, T. Roudier)

7. Processed data (FITS) : in project The Pic du Midi instruments THEMIS  The MSDP Mode  B// and V// maps  The MTR Mode  Stokes parameters  B// and V// maps  Vector magnetic field Extrapolation (FROMAGE) Data selection Use of a « standard » code Data availability

8. THEMIS data request Currently:  Date, Hour, Wavelength, Instrument, Coordinates, Object 6 criterions used for the request Problem: this is too large ! Example in MTR:  Sunspot in Hα: 32 sequences  Active region in Hα: 144 sequences  Sunspot at 6302 Å: 83 sequences  Prominences in Hα: 42 sequences Too many Go for the users !

9. Project for the 2002 campaign if the keywords are validated:  Seeing, Simultaneous preslit / field-of-view observation,  Stokes sequence  Scan parameters  Campaign, NOAA number After 2003:  Raw / processed (physical parameters)  Active mirror 14 criterions used for the request New request form Restricted request necessary

10. Service to the users Diffusion of codes  Data processing codes  Radiation transfer, Line formation depth ? Organization of workshops about THEMIS data processing:  MSDP : February 2002 / Fall-winter 2002  MTR : Fall-winter 2002 Information about the calibrations and observing conditions

11. Relations between databases With BASS2000 – Meudon  Solar survey archive / Long term archive  Common web page  Harmonization for future common requests With MEDOC  Future requests MEDOC Tarbes  Successful tests have been performed

12. Conclusion Data diversification  Producers  Added value New services  Data processing workshops  Diffusion of codes, … Importance of data perennization  Observing files headers  Observing forms  Interesting events and problems  Calibrations Web : http://bass2000.bagn.obs-mip.fr
