In the published article, due to our typing mistake, Equations (8) and (9) were incorrect. We wish to correct the definition as follows:

$\begin{eqnarray}&&\cos {\theta }_{1}(t)=\sin {\psi }_{1}\cos (\omega t+{\phi }_{1})\sin i+\cos {\psi }_{1}\cos i,\end{eqnarray} \tag{ 8 }$

$\begin{eqnarray}&&\cos {\theta }_{2}(t)=\sin {\psi }_{2}\cos (\omega t+{\phi }_{2})\sin i+\cos {\psi }_{2}\cos i\end{eqnarray} \tag{ 9 }$

where θ₁ and θ₂ are the viewing angles of the two jets. Equations (8) and (9) here are identical to the expressions in Equations (1) and (2) in Qian et al. (2007).

This correction does not have any effect on our final results, since this error only occurred during typing. Both equations used in our corresponding calculations are correct.
