Davos consortium discussion

Possible topics 1.Interests common to PREMOS, SOVAP, SODISM 1.New lab experiments 2.cross calibration 3.Onboard synchronisation 4.validations 2.CMSP issues 1.New operations (feasibility, definition, implementation) 2.Review of the CMSP algorithms (completeness, usefullness, future usage...) 3.Review of PICARD scientific objectives 1.Complete? 4.AOB??? 5.Actions and conclusions to be communicated to the PICARD-SC

PICARD science objectives 1.Measurement of the profiles of the solar limb 2.Measurement of the photospheric diameter 3.Inference of the helio-seismic diameter 4.Detection and characterization of solar intensity oscillations, and esp. g modes 5.Accurate, precise and redundant measurements of the TSI 6.Contribution to the estimation of the spectral irradiance 7.Measurement of the photospheric differential solar rotation 8.Measurement of the asphericity of the solar disc 9.Assessment of the magnetic activity and delivery of SpW information 10.Studies of the Earth atmosphere via e.g. solar occultations during eclipse seasons, albedo studies with BOS, etc. 11.Contribution of PICARD to the understanding of Sun Earth connection processes 12.Room must be kept for serendipity…

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

CMSP issues Validation means – Verifying that PICARD data match previous knowledge – Assuring data quality from inner instrumental understanding GT: 1.Reprocessing very difficult as of today 2.Uploading new command difficult 3.Uploading frequent commands not prefered All: update the commitments so as to meet minimal success (data quality, and thus reprocessing)
