Notes. Columns 2–4 report effective magnitude and effective radius for the inner component of each fit. The Sérsic index for the in situ 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 allows us to obtain a better fit. Columns 5–7 list the same parameters for the second component, whereas Cols. 8 and 9 list the central surface brightness and scale length for the outer exponential component. Columns 10–12 report the total magnitude of the inner Sérsic (mT,1) and outer components (mT,2 and mT,3). Column 13 gives the total accreted mass fraction derived from our three-component fit, while Cols. 14 and 15 report the transition radii between two fit components.
