Rows 1 and 3 show in purple the histograms of the resulting parameters for the AGN sample when using GoMar23 model. We use the same bins as those used for the SED grid. Rows 2 and 4 show the histogram of the relative importance of each parameter in the convergence of the fit. It is obtained as the maximal variation of χ² for each parameter range compared to the parameter giving the maximum variation, denoted as Δχ² (see Fig. 11). Each panel also shows the percentage of objects with Δχ² above 5 and 95%.
