Structure of the data analysis process. “coron” stands for “coronagraphic”, “bd” for “background”, “foc” for “on focus” (the DM is flat), and “div” for “diversity”. The COFFEE reconstruction is done independently but with the same method in both configurations (direct and coronagraphic) for comparisons later on. The segment pistons extracted in both cases will also be compared to the commands sent to the Iris-AO segmented mirror.
