Demonstration that GC velocity dispersion profiles can be fitted easier by a ΛCDM model than by a MOND model even if the models omit some important aspect (e.g., halo stripping or perturbed GC kinematics). Blue lines indicate 100 random ΛCDM models of the velocity dispersion profile of NGC 1399, according to the statistical distribution of the free parameters described in Sect. 5. Such free parameters are well consistent with all the observational and theoretical constraints we have on the galaxy. Red lines indicate the same for the MOND models. Green line indicates the observed velocity dispersion profile of NGC 1399.
