Distribution and kinematics of diffuse ionised gas in MR 2251−178 (left-hand panels) and PG 1126−041 (right-hand panels). For each system, the set of six panels on top (middle, bottom) show the moment-0 (moment-1, moment-2) map for the [O III] (first row) and the Hα (second row) emission lines from diffuse gas. The different columns show the maps derived for the whole line, or for the LV and the HV components separately. Moment-1 and moment-2 maps are clipped at a peak S/N of 3. Moment-1 maps are relative to the systemic velocity of the QSOs, given by their estimated redshift.
