Isotropic spherical Jeans models compared to the kinematic data of NGC 2808. Stars correspond to the inner kinematic profile obtained with integral-field spectroscopy and bullets represent the data obtained with the Fabry-Perot instrument. Shown are a model with a constant M/L_V over the entire radius of the cluster (black line) as well as the model where we fit an M/L_V profile (green line). The resulting M/L_V profile is shown in b) together with the constant value of the previous model.
