Continuum subtracted moment-0 maps of the CIV, HeII, CIII], and CII] emission lines. The continuum is determined from the nearby line free channels for each line. Panel A): sum over the CIV emission line for the wavelength range λ_obs = 6050−6090 Å. Panel B): sum over the HeII emission line for the wavelength range λ_obs = 6422−6430 Å and is the same image as the blue colour of the middle panel of Fig. 5. Panel C): sum over the CIII] emission line for the wavelength range λ_obs = 7455−7485 Å. Panel D): sum over the CII] emission line for the wavelength range λ_obs = 9071−9171 Å. Over-plotted with yellow contours in all panels is the VLA radio map, as a reference.
