Sinograms presenting the organisation of median-AF (left) and binned-SM (right) window fluxes of a simulated elliptical galaxy (ellipticity = 0.7, position angle = 45 deg, effective radius = 2500 mas and Sérsicindex = 3). Each horizontal line of the sinograms corresponds to one transit. AF windows are 12 samples long, while SM are 20 samples long. The fluxes of the AF and SM windows with transit angles = 0 deg lie at the bottom of the sinograms and the ones at 180 deg at the top. The colour scales designates the sample flux values expressed in e−/s.
