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
