Internal comparison of the parameters obtained for galaxies with the Sérsic profile and with the de Vaucouleurs profile. Left and middle panels: internal comparison of the position angles and ellipticities of galaxies obtained with the Sérsic profile and with the de Vaucouleurs profile. Right panel: comparison of effective radii from the Sérsic profile and from the de Vaucouleurs profile, for a selection of sources that have a Sérsic index of close to 4, corresponding to typical elliptical galaxies well represented by a de Vaucouleurs profile.
