SpaceInn Global Helioseismology Team Meeting

The meeting will start March 11, 2015 at 14:00 and will end on  March 13, 2015 at 12:30. The meeting venue is the Kiepenheuer-Institut für Sonnenphysik in Freiburg, Germany.

Draft program:
We need to review the actions of the previous meeting.

  • Presentations on activity (new paper based on GOLF done by David)
  • Progress on low-frequency analyses
  •  Development of a new simple code for fitting helioseismic data
    • Based on Diamonds (Bayesian public code by Corsaro)
    • a general MLE code
  • Progress on combining data of different instruments
  • Presentation of the deliverable (S_ph)
  • New global helioseismic techniques
  • Discussion on the frequency of updating (every 3-4 months)



This program is a draft and heavily under construction:
