Surface density profiles of GCs of five of the galaxies from the sample obtained using spectroscopic data. A power law is fit with the solid red lines to the radial surface density of GCs: N_cl ∝ R^{− γ} for two galaxies (NGC 1400 and NGC 2768). For the remaining three galaxies, the Sérsic fit, determined by the parameter n is also presented using the dotted blue lines: in such cases, a power law is fit in the inner and outer regions separately with the solid red lines (see text for details).
