\caption{Times for the different phases in the evolution of the
perturbed jet models. $t_{\rm lin}$: end of linear phase (the
amplitudes of the different quantities are not constant any
longer). $t_{\rm sat}$: end of saturation phase (the amplitude of the
transverse speed perturbation reaches its maximum). $t_{\rm mix}$: the
tracer starts to spread.  $t_{\rm peak}$: the peak in the amplitude of
the pressure perturbation is reached. $t_{\rm mex}$: the jet has
transferred to the ambient~1\% of its initial momentum. $\Delta_{\rm
peak}$: relative value of pressure oscillation amplitude 
at the peak of pressure perturbation (see Fig.~\ref{fig:amplitudes}).\label{tab:phases}}
