Posterior probability distributions of the renormalization factor of the S​_X,  sat profile: 𝒩_sat, and the normalization of the point source component: 𝒩_ps, which are obtained by fitting the forward-model 3 from this work to the Full_phot data points from Z24 shown in Fig. 3. The vertical red lines in the diagonal plots correspond to the most likely value; the respective values are mentioned in the titles (refer to Table 1). The dashed black lines are the 68% confidence interval of the marginalized distribution of the free parameters. The contour plot marks the most likely values with the red cross, and the contours correspond to the 68%, 95%, and 99.7% confidence intervals.
