Radiative age (left) and associated error (right) maps obtained from the fit of a Tribble model with B = 1.8 μG and Γ = 0.55. The radiative age increases from the centre to the outer regions: the jets are 10 ≤ trad ≤ 20 Myr old, the primary lobes are 20 ≤ trad ≤ 30 Myr old, and the inner parts of the wings are 30 ≤ trad ≤ 40 Myr old. Typical errors are < 5 Myr.
