Helioseismology with PICARD

Préparation du programme d’hélioseismologie de PICARD: 

  • Rédaction avec l’IAS et B. Gelly (Thémis) du document de spécification pour l’heliosismologie PICARD.
  •  Développement des algorithmes "Quick Look" (Niveaux N1, N1p) pour le Centre de Mission Scientifique PICARD (CMS-P) à Bruxelles.
  • Mise en place d’un Centre de Traitement (CT-OCA) pour l’analyse des images PICARD et SDO.

Symmetric part of the internal solar rotation rate with respect to the equator. Iso-contours are shown every 10 nHz from 300 nHz up to 480 nHz. This was obtained by inverting the frequency splittings estimated from PICARD/SODISM intensity images over the period from April 16 to November 10 2011. The solution below 0.3 solar radius is poorly constrained by the data and is not shown.
