Relations between parameters of the UV outflows and other AGN parameters in the SUBWAYS HST sample. In the corner of each panel, the Spearman’s rank correlation coefficient, r_s, and the null hypothesis probability, p_null, are given. In panels with statistically significant correlations (p_null < 0.05) the data points are displayed in magenta and in those with no significant correlation in blue. The UV measurement uncertainties are displayed in this figure, however, they are significantly smaller than the explored scales.
