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

Status

Integrated data: THEMIS 1999-2001 : 2063 Go (1635 sequences) NRH 1999-2001 : 192 Go (833 sequences)

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 !

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

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

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

Conclusion Data diversification
