Fig. 7
Velocity field of the [O iii] EELR around HE 2158 − 0107. Left panel: radial velocity map inferred from the [O iii] emission line Doppler shift with respect to the rest-frame of the QSO. The black solid line represents roughly the apparent kinematic major axis. Right panel: radial velocity curves extracted from the velocity map along the kinematic major axis (black open circles).
