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

  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 MSDPMode • 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. Restricted request necessary • 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

  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
