Results of the mock analysis. The input parameters used to build the mock catalogue are shown on the x-axis while the results of the fitting of the mock catalogues are shown on the y-axis. A good constraint on a given parameter is obtained when there is a one-to-one relationship, which is indicated by the black solid lines. Grey dots are all sources selected from the Aufort et al. (2020) sample while blue circles are the galaxies composing the final sample.
