Rotation over dispersion ratio A_total/σ as a function of: current mass (top left) (Baumgardt et al. 2023b), relaxation time (top right) (Baumgardt et al. 2023b), enriched star fraction (bottom left) (Leitinger et al. 2023) and concentration parameter (bottom right) (Harris 2010). Clusters are colour-coded by $A_4^{+}$ values (Leitinger et al. 2023) and each panel shows the Spearman and Pearson rank correlation coefficients for each parameter, with corresponding log p-values to show the significance of the correlations (log(p) ≤ −1.3 indicates a p-value ≤ 0.05, meaning the correlation is statistically significant and not a result of random chance).
