Notes. Columns 2, 3, 4, 5 report the effective surface brightness, effective radius (in arcsec and kpc scale) and Sérsic index for the inner component of each fit, in the g band, whereas columns 6, 7, and 8 list the central surface brightness and scale length for the outer exponential component, in arcsec and kpc scale. Columns 9 and 10 give a transition radii, in arcsec and kpc scale respectively, derived by the intersection between the first and the second component of the fit Appendix A.
