Probability distribution functions for the five parameters of the inference on the properties of the combined velocity and metallicity distribution of C-19 members. The five parameters are the fraction of contaminants, η, and the mean and dispersion of the velocity (⟨v_r⟩ and sigma_vr) and metallicity (⟨[Fe/H]⟩ and σ[_Fe/_H]) parts of the model. The top panel of each column shows the one-dimensional marginalised probability distribution functions from which the favoured parameter models and related uncertainties are determined. The red contours and histograms show the same after the three likely contaminant stars are removed and the MW contamination is fixed to η = 0.
