99.9th percentile velocity of the LoSVD of the ionised gas as traced by the [OIII] (top panel) and Hα (middle panel) emission lines, and of the stars (bottom panel). For a Gaussian velocity distribution, the 99.9th percentile velocity corresponds to +3 standard deviations (3σ) from the mean velocity. Similarly to Fig. 14, we report the Spearman rank correlation coefficient ρ for each plot, along with its associated two-sided p value.
