Sample comparison of outflow parameters. Panel a: outflow velocity as a function of the ionization parameter. AGNs on the right side of the dashed gray line host potentially magnetically driven winds, see text for details. Panel b: ionization parameter versus the outflow equivalent column density. The gray arrows represent the upper/lower limits for the log(ξ) and N_H values (see Table A.2). The S23 UFO sub-sample is shown in red circles, T10 in blue diamonds, and C21 in black squares. The dashed magenta lines show the median value of each sub-sample.
