Model of the bulk jet precession fitted to the TXS 0506+056 data. We performed a simultaneous least-squares fitting to the flux density of core I, and the apparent velocities and position angles of jet I. Top row, left panel: precession model fitted to the flux density of the core I (blue points). Time is in units of years and the flux density in units of janskys. Middle panel: precession model fitted to the apparent velocities of the jet I components (1a, 1a1, and 1a2) at the estimated time of their ejection. The apparent velocities are in units of the light speed. Right panel: precession model fitted to the position angles of the jet I components at the estimated time of their ejection. Position angles are in degrees. Middle row: as in the top row, but the fitting was performed for the fixed Doppler-boosting exponent of ξ = 1.5. Bottom row: same as above, but for the fixed Doppler-boosting exponent of ξ = 3.0.
