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
