Notes. Best-fit parameters of the double-Sérsic fit to the surface brightness profile of the BCG+ICL in IE and HE, and the GC surface density profiles around NGC 1275+ICGC and the nearby massive elliptical NGC 1272. For each component, ae and µe list the half-light radius along the semi-major axis and the surface brightness at the half-light radius, respectively. Total luminosities, Ltot, and luminosities within 500 kpc of the BCG, L<500kpc, are corrected for extinction. Ntot (N<500kpc) is the total number of selected GCs with IE < 26.3 (and within 500 kpc), after background subtraction. The uncertainties are either the statistical uncertainties of the best-fit Sérsic parameters or, for L and N, propagated uncertainties of the best-fit Sérsic parameters using 1000 Monte Carlo realisations.
