Notes. Best-fit parameters of the PSF-deconvolved light profile decomposition: Col. 1: number of functions of the multi-component fit applied. Columns 2–4: effective radius, Sérsic index, and effective surface brightness of the first Sérsic component. Columns 5–7: effective radius, Sérsic index, and effective surface brightness of the second Sérsic component. Columns 8 and 9: scale radius and central surface brightness of the exponential component. Column 10: accreted mass fraction.
