Maps of w₈₀ (top left), v₅₀ (top right), v₁₀ (bottom left), and v₉₀ (bottom right) of the [O III] emission line. These maps provide an overview of the widths and velocity shifts from the entire [O III] profile. In each panel, the black thin contours represent the S/N levels shown in Fig. 4. The black thick contours in the center of the figure depict the molecular outflow, detected in B19. These contours correspond to the emission levels of 1, 4, 8, and 10 mJy. The white cross gives the position of the quasar. The white lines in each map represent 2σ Gaussian-smoothed contours that enclose the regions where w₈₀ exceeds 400 km s⁻¹.
