DPI data is displayed as a reference in the top row, together with the best-fit models (left) and the corresponding residuals (right) resulting from the grid-search (second row), and the MCMC (third row) analysis methods. Table 2 provides the parameters of the model for these two cases. The ellipses in dashed white lines show the aperture within which the reduced χ² minimization has been performed. The bottom row shows the deprojected density function corresponding to the MCMC best-fit model.
