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.

"GROUND PICARD" is a set of 4 ground based instruments which are operated at the Calern facility of the Cote d’Azur Observatory during the space mission PICARD .The goal is to measure the solar shape simultaneously from space and ground and to learn how to interpret ground measurements through a detail analysis of atmospheric effets (read more...). This project is a collaboration between LAGRANGE (OCA), LATMOS (IPSL) and CRAAG (Algiers) and is supported by the french spatial agency (CNES) as part of the PICARD mission.
