3D Reconstruction Techniques for the Stereo Mission

Scientific objectives

The twin satellites of the Stereo mission, to be launched mid-2006, will allow us to view the three-dimensional (3D) heliosphere for the first time and with an unprecedented combination of imaging and in situ experiments. Stereo will face the community with new problems that require 3D reconstruction tools.

Many visualisation and analysis techniques have been developed for Stereo or are under development. They are listed on the Secchi 3D reconstruction web page. Yet there remains an important need for closer interaction between all these different initiatives, finding for examples ways how different approaches can be combined to improve the reconstruction. This has motivated the creation of a small team that would seek a better coordination among european contributions to Stereo while keeping a strong connection with the rest of the community.


This team will deliver a web-based interface with : The web interface will be made available during the Stereo-Secchi meeting that is planned to take place in Orsay a few months after the launch of Stereo.
