  • 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

      • The MSDPMode
        • B// and V// maps
      • The MTR Mode
        • Stokes parameters

Data availability

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 !

slide9

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

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
