Notes. Columns 2, 3, and 4 report the effective surface brightness and effective radius for the inner component of each fit. Columns 5, 6, 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. Column 10 gives the accreted mass fraction derived from our fit. Column 11 reports the total stellar mass, while Cols. 12 and 13 report the transition radii derived by the intersection between the first and the second component of the fit and the second and the third component, respectively. Columns 14, 15, and 16 give the effective radii, absolute magnitudes in the r band, and average (g − i) colours from Iodice et al. (2019b)
