Model fitting of the kinematics for knot f: trajectory Zn-Xn, core separation rn(t), coordinates Xn(t) and Zn(t), the modeled apparent velocity/viewing angle and Lorentz/Doppler factor. Its ejection time is assumed to be t0 = 1995.66 (BQS17). Two curvatures in its trajectory at Z = 9 mas and Z = 40 mas (corresponding to core separations rn = 0.30 mas and 1.0 mas) are introduced.
