Radius r_10,c expressed in units of r_max as a function of the galaxy mass, effective radius r_e, and Sérsic index ν (the function z_10,c(θ,ν) in Eq. (20)). Above this radius, circular velocity differs by less than 10% from its asymptotic value. The MOND transitional radius r_M is connected to the mass of the galaxy by Eq. (19). The radius r_max is defined as the maximum of r_e and r_M. The ratio r_M/r_e can be determined observationally from Eq. (22). The circles denote the galaxies from the ATLAS^3Dsample of local elliptical and lenticular galaxies.
