Multifrequency RATAN-600 radio light curves of TXS 0506+056 at 1.2–22 GHz (markers with 1σ uncertainties), shown with vertical offsets of 2 Jy between adjacent bands for clarity. The solid curves correspond to Scenario C (redissipation followed by jet deceleration). The vertical dashed line marks the onset of the deceleration phase, after which the Doppler factor is assumed to decrease as a power law. For each band, the thin horizontal dashed line indicates the estimated quiescent/background level.
