Table 2: 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. $t_{\rm fmix}$: external material reaches the jet axis. $t_{\rm mex}$: the jet has transferred to the ambient a 1% of its initial momentum. $t_{\rm meq}$: longitudinal momentum in the jet and the ambient reach equipartition. $\Delta _{\rm peak}$: relative value of pressure oscillation amplitude at the peak (see Fig. 1 of Paper I). Note that, as a general trend, $t_{\rm lin} < t_{\rm mex} \approx t_{\rm mix} <t_{\rm sat} <t_{\rm peak} <t_{\rm fmix} < t_{\rm meq}$.
