Notes. Column (1) reports the empirical law adopted for the multi-component 1D fit. Columns (2)–(4) list the effective surface brightness, effective radius, and Sersic’s index of the Sersic law for each of the two inner components. Columns (5) and (6) list the central surface brightness and scale length of the exponential component adopted to fit the galaxy envelope.
