Spectral index maps of the inner jets. The maps are between 144 MHz and 3 GHz (left), 3 GHz and 5.5 GHz (center), 5.5 and 9 GHz (right), displayed with a matching color-scale of 0 ≤ α ≤ 2. Contours from the 3 GHz map used for the spectral index are overlaid. The relative uncertainty on the spectral index range between 2.5% – 15% (144 MHz–3 GHz), 6% – 15% (3 GHz–5.5 GHz), 7% – 30% (5.5–9 GHz). Structures discussed in this work are labeled.
