Comparison of observed kinematics and the finite mixture model in NGC 3311. Top panels: observed four moments of the LOSVD in a Gauss-Hermite expansion, including systemic velocity (V), velocity dispersion (σ), and two high-order moments for the skewness (h₃) and kurtosis (h₄) of the distribution. Middle panels: best fit for the finite mixture model according to parameters in Table 2 (see text for details). Bottom panels: residuals between the observed fields on top and the best fit models in the middle panels.
