Top left panel: column density of the ionised AGN wind components versus their ionisation parameter. The red squares correspond to the first xabs component of the wind, while the blue circles correspond to the second xabs component for those AGN with two ionised wind components (see Table 3). Top right panel: total column density of the ionised AGN wind versus the intrinsic X-ray luminosity of the AGN over 0.3–10 keV. Middle left panel: total column density of the ionised AGN wind versus the inclination angle of the radio jet relative to our line of sight. Middle right panel: total column density of the ionised AGN wind versus the ratio of mid-IR to optical flux density (i.e. the “mid-IR loudness” parameter of the dusty torus). Bottom left panel: total column density of the ionised AGN wind versus the mass of the SMBH. Bottom right panel: total column density of the ionised AGN wind versus the Eddington ratio (ratio of bolometric to Eddington luminosity). The Spearman’s rank correlation coefficient r_s and the null hypothesis probability p_null of the correlation between the parameters are shown in the corner of each panel.
