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 Ha 32 sequences
• Active region in Ha 144 sequences
• Sunspot at 6302 Å 83 sequences
• Prominences in Ha 42 sequences

Too many Go for the users !
