Additional FEL spectro-images. Left: Blueshifted jet channels (−140 km s⁻¹ to +90 km s⁻¹) in Field B before and after deconvolution. Contours are as in Fig. 2, starting at 3-σ of the background rms level pre-deconvolution, approximately 10 × 10⁻²⁰ erg s⁻¹ cm⁻² (26 × 10⁻²⁰ erg s⁻¹ cm⁻² for the [O III]λ5007 spectro-images due to higher background noise). In [O I]λ6300 the starting contour is 2-σ (10 × 10⁻²⁰ erg s⁻¹ cm⁻²) to highlight the faint emission in this lobe. Right: Same, but for the redshifted velocity channels (−90 km s⁻¹ to +140 km s⁻¹) in Field A, with contours as in Fig. 3.
