Top: spatial distribution of the normalized flux along the slit of Lyα (blue), C IV (green), and He II (orange). Negative and positive values of θ correspond to PA = 110° and 290° (measured north to east), respectively. Continua have been subtracted. Bottom: Lyα spectral FWHM (already corrected from the instrumental broadening). Arrows represent the FWHM upper limits (≃650 km s⁻¹). The spatial zero marks the location of source A, whereas the approximate positions of VLA radio components are marked with red dashed lines.
