The LESIA (http://www.lesia.obspm.fr/) is strongly committed to PLATO, both in terms of embedded software, the specification of on-board and on-ground processing algorithms, and the scientific preparation of the mission. As part of the mission development phase, one of the tasks to be carried out concerns the study and specification of all on-ground algorithms. These specifications are indeed essential to begin with the development of the on-ground data processing chains. This work is conducted under the responsibility of the LESIA (respectively R. Samadi) in the framework of WP 32 (a component of the Plato Data Center, PDC). It involves many collaborators in close contact with the team responsible for the development of the on-ground software at the Max Planck Institute in Gottingen (Germany).

At this stage of the project, the main components of the on-ground data processing chains are identified. However, the corresponding algorithms have to be studied in detail and complete evaluations of the expected performances have to be made. Finally, it will be necessary to translate the algorithms, currently in the form of detailed specifications, into a set of documents on the basis of which the PLATO Data Center (PDC) team will then develop the codes and perform the validation and integration tests.

The 10th meeting of the DPA-WG is taking place on October 11th and 12th, at Observatoire de Paris. Attendance is by invitation only.
