General structure of the data processing. The turquoise (filled) boxes are modules developed specifically for Solar System objects, which run on the servers of one of the Data Processing Centers of Gaia (CNES in our case). White boxes represent input and output data. Yellow boxes are tasks that are developed, managed, and run by the Solar System scientific team that are essential to the preparation of the input data or to the validation of the output. Other modules providing input data, developed by other teams, are initial data treatment (IDT), intermediate data updating (IDU), the astrometric global iterative solution (AGIS), and the photometric pipeline (PhotPipe).
