Flow chart giving the steps to simulate the interferometric data mimicking CHARA/SPICA observations. The pipeline carries out a Hankel transform on the intensity profile from the stellar radiation transfer calculations, using the UV coordinates and wavelength from Aspro2. The error is added to the square visibility, taking S/N = 20 and generates an error with a random extraction for each point in the square visibility. Input and output are shown in parallogram (grey) and intermediate processes are shown in rectangle (black).
