Narrowband channel maps of [O III]λ5007 emission in 4C03+24. Each panel shows the spatial distribution of [O III] flux along successive spectral slices from the blueshifted side of the line (v ≈ −1900 km s−1) to the redshifted side (v ≈ +1010 km s−1) in ∼3–4 Å intervals. The blueshifted slices reveal a compact [O III] morphology, primarily coincident with the radio core. As the velocity approaches the systemic redshift of the galaxy, the ionized gas becomes significantly more extended and luminous, connecting the central radio source with the southern radio lobe. In the redshifted slices, the nebular emission becomes more compact again, with enhanced flux localized near the northern and southern extremities of the galaxy.
