Notes. The break frequency (νbreak) and the synchrotron age (t) derived from the fitting model, the adiabatic-loss corrected break frequency (
) and synchrotron age (tcorr) and finally the reduced chi-squared of the fit (
). Those parameters are derived for both the total age (Tot), the dying phase (Off) and the active phase (On) of the lobes using two different models (Tribble and CIoff), setting αinj = 0.75 and Beq = 5.9 μG.
