\caption{Times for the different phases in the evolution of the
perturbed jet models. In Cols.~2$-$4 we show: $t_{\rm lin}$ -- end of
linear phase (the ratios of 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),
$t_{\rm peak}$ -- the peak in the amplitude of the pressure
perturbation is reached. (see Fig.~\ref{fig:amplitudes}). Note that,
as a general trend, $t_{\rm lin} < t_{\rm sat} \leq t_{\rm peak}$.
In Col.~5 we show the saturation time in dynamical time units and
in the jet reference frame.}
