Diagnostics of initially mass segregated star clusters with 1 k members following the prescription of Šubr et al. (2008). From top to bottom the degree of mass segregation, S, equals 0.1, 0.3, and 0.9 (see text for more details). On the left-hand side we compare Γ_MST and Λ_MST for the 5, 10, 20, 50, 100, 200, 500, 1000 most massive stars. The error bars and line thickness mark the 1σ, 2σ, and 3σ uncertainties. On the right-hand side we plot the corresponding mass function of the entire cluster population (solid black line), and the population within one (red tics), one-half (green crosses), and one-forth (blue dots) half-mass radius. The error bars mark the 1σ uncertainties.
