Notes. Columns 2–4 report effective magnitude, effective radius, and Sérsic index for the inner component of each fit. The Sérsic index for the first component was fixed to n ∼ 2 using the models as a prior (Cooper et al. 2013). We allowed small variations of ±0.5 around the mean value of n = 2. This would bracket the range of n in the simulations and allowed us to obtain a better fit. Columns 5–7 list the same parameters for the second component, and Cols. 8 and 9 list the central surface brightness and scale length for the outer exponential component. Cols. 10–13 report the transition radii between two-fit components in arcsec and in kpc, respectively, while Col. 14 gives the total accreted mass fraction derived from our three-component fit.
