Presentation Transcript

  1. Davos consortium discussion

  2. Possible topics • Interests common to PREMOS, SOVAP, SODISM • New lab experiments • cross calibration • Onboard synchronisation • validations • CMSP issues • New operations (feasibility, definition, implementation) • Review of the CMSP algorithms (completeness, usefullness, future usage...) • Review of PICARD scientific objectives • Complete? • AOB??? • Actions and conclusions to be communicated to the PICARD-SC

  3. PICARD science objectives • Measurement of the profiles of the solar limb • Measurement of the photospheric diameter • Inference of the helio-seismic diameter • Detection and characterization of solar intensity oscillations, and esp. g modes • Accurate, precise and redundant measurements of the TSI • Contribution to the estimation of the spectral irradiance • Measurement of the photospheric differential solar rotation • Measurement of the asphericity of the solar disc • Assessment of the magnetic activity and delivery of SpW information • Studies of the Earth atmosphere via e.g. solar occultations during eclipse seasons, albedo studies with BOS, etc. • Contribution of PICARD to the understanding of Sun Earth connection processes • Room must be kept for serendipity…

  4. New lab experiments, new operations • Filters • Common interest of PREMOS and SODISM • Straylight: sodism2 versus sodism3 • WS: would the ‘moon’ move with the pointing? • Issue of getting a forecasted mode into operation • List and prioritize the wanted new operations • BOS experiences a crosstalk effect

  5. CMSP issues • Validation means • Verifying that PICARD data match previous knowledge • Assuring data quality from inner instrumental understanding • GT: • Reprocessing very difficult as of today • Uploading new command difficult • Uploading frequent commands not prefered • All: update the commitments so as to meet minimal success (data quality, and thus reprocessing)
