Range of stellar surface stellar magnetic field distributions used in the two models. Top: bimodal distribution model. Bottom: single Gaussian model. Both models are shown here for a cluster of 10⁵ M_⊙ and a Salpeter IMF. Each color corresponds to a set of parameters for each distribution: (μ₁, μ₂, f₂) for the bimodal, and μ for the Gaussian. The dispersion of each distribution with mean μ_i is set to σ_i = 0.1μ_i.
