| Abstract: |
The light curve, polarization properties and VLBI structure of OJ287 are explained in terms of a precessing jet model. All the geometrical parameters of the jet are determined from the velocities and position angles of the superluminal features. The Lorentz factor of the relativistic jet is completely determined by the shape and duration of the periodic optical outbursts. |
