Fig. 1.
Scheme of the torus-jet model. The jet is parametrized by the angles θ1 and θ2 that describe the angular opening of the radiation-emitting sheath, by the base height zb, the constant Lorentz factor Γj, and the temperature power-law index sT. The jet is symmetrical with respect to the equatorial plane, and axisymmetric.
