Upper panel: radial velocities of the confirmed GC member stars versus radial distance from the centre of NGC 4372. The red curves indicate ± 3 times the velocity dispersion as a function of the radial distance. The vertical dashed lines indicate the borders of the bins used to compute the velocity dispersion at a given radius. Bottom panel: velocity dispersion profile of NGC 4372 together with the best fitting Plummer profile (thick red line) and the rotating model (thick black line). The shaded area between the two thin red lines indicates the 1σ uncertainty of the Plummer profile.
